SUMMER 2013 EDITION RS News Rett Syndrome Association Scotland “David & Victoria setting off at the start of the Coast to Coast Relay for Rett 2013” In this issue: Mark Bailey Report • RS Europe • Music Therapy Booklet Badaguish • Roadshow • Relay Report Eurordis • Accounts • AGM • Future Events Fish Oil Dr Jane McKenzie, Senior Lecturer in Biochemistry and Metabolism and Programme Leader for BSc Human Biology, Queen Margaret University College, Musselburgh Back in February a member contacted the Association with a query about the use of Norwegian Fish Oil, which she hoped would be of benefit to her Rett daughter. Unfortunately the cost of the oil was high - £31 per bottle and she wondered if there was anything else suitable but cheaper. At about the same time an article appeared in the Herald newspaper regarding a programme set up to test the amount of Omega-3 fatty acids a family would consume over a six week period, the aim being to improve the nations’ health by encouraging people to include more Omega-3 in their diets. This programme had been designed by expert nutritionists at Queen Margaret University College in Musselburgh. Dr Jane MacKenzie, Senior Lecturer in Biochemistry and Metabolism and Programme Leader for BSc Human Biology at the University was contacted and she has very kindly provided us with the following information:“The evidence for a potential benefit of long-chain omega-3 fatty acids (often referred to as EPA and DHA found in Fish Oil) in Rett Syndrome is currently very scarce, but could be promising. I believe that the most recent paper, which can hopefully be accessed through this link www.ncbi.nlm.nih.gov/pmc/articles/PMC3380188/, does indicate potential benefits from taking very large doses of fish oil, however only a very small number of participants were involved and the study has not been repeated as yet. My opinion is therefore that the benefits of fish oils in reducing the symptoms of Rett Syndrome need to be confirmed with further research before we are able to recommend the use of fish oil or indeed the appropriate dose to use. The fish oil supplement used in this research is Norwegian and likely the one that was mentioned at a cost of £31 per bottle, which is indeed very expensive. The active ingredients of any fish oil (the EPA and DHA) are equivalent regardless of where they are produced, although there are differences in the amount of these fatty acids provided by commercially available products. Therefore, I do not believe that there is any reason to use the specific fish oil used in this study, particularly as it is sold at a premium price! However, if your members feel that they want to provide their child with fish oils based on the existing evidence, then there is no reason not to, but I would suggest that they purchase a cheaper fish oil product – as we do not know what might be an appropriate dose, I would suggest a ‘high EPA/DHA’ product providing around 450mg (DHA+EPA) per day which is the recommended dietary dose to gain some health benefits related to maintenance of eye and brain function and reducing the risk of heart disease.” Dr McKenzie has also sent the following article for our information:- IMPROVING OMEGA-3 INTAKES OF PRESCHOOL CHILDREN IN THE UK Dr Jane McKenzie PhD RD, Senior Lecturer in Biochemistry and Metabolism, Queen Margaret University, Edinburgh, Scotland. The benefits of long chain omega-3 fatty acids (LC n-3 PUFA) in childhood are extensively documented. Not only do they play a key role in optimizing cognitive, behavioural and visual development(1), but they also provide protection against the development of cardiovascular disease(2). Breast milk provides a reliable source of LC n-3 PUFA during infant development and the majority of infant formulas are supplemented with these fatty acids in an attempt to mimic the composition of breast milk and offer the same benefits. However, as a child is weaned, there is increased reliance on dietary sources of LC n-3 PUFA. Oily fish provide the only significant source of naturally occurring LC n-3 PUFA in our diet. According to the 2009 National Diet and Nutrition Survey(3), however, the average intake of oily fish in children aged 3-5 years of age is just 24.5g per week, and this is primarily attributed to the relatively few children consuming oily fish on a regular basis. So why are intakes of oily fish so low in this population? Unfortunately, many negative preconceptions exist which appear to inhibit the incorporation of oily fish into children’s diets. Aside from the apparent strong taste and smell(4), oily fish is considered expensive as there is a lack of confidence about how to prepare and serve it(5). In addition, despite assurances to the contrary, oily fish are often associated with the ingestion of pollutants which may put health at risk(6). These influences are particularly pertinent for children growing up in areas of deprivation, where eating habits are already suboptimal and resistant to healthy eating messages(7). Preschool provides a suitable environment for introducing and reinforcing positive eating habits. In particular, the immediacy of developmental needs for LC n-3 PUFA would suggest that this is the ideal opportunity to influence preferences for oily fish. An initiative was therefore set up to develop and evaluate a range of omega-3 rich snack foods, containing oily fish, provided to children attending a nursery in a deprived area of Scotland(8). Acceptability and subsequent consumption of the omega-3 rich snacks was comparable to that of the regular snacks, yet provided a valuable 250mg more LC n-3 PUFA per portion. These findings indicate that oily fish can be successfully introduced into the diet of preschool children and that such an initiative can contribute to achieving current recommendations for LC n-3 PUFA intake.

Presented at the Scottish Lipid Discussion Group Meeting, Stirling, June 2010 Also, an item appeared in the minutes of the General Assembly of Rett Syndrome Europe, London, 17th November 2012 as follows:- FISH OIL RSE has been approached by the Norwegian Fish Oil Company to promote their product. They say that their product is very pure. The company has made extravagant claims about the benefits of their fish oil. They say that the membrane in red blood cells is abnormal. The product has been given to young girls and therefore it is difficult to see if the improvement is developmental or as a result of taking fish oil. It would need to be followed up scientifically. A trial costs a lot of money, for instance the clinical trial in France about desipramine for 36 people with RS costs about 500,000¤ . It is debatable if there is enough evidence to conduct a trial.” Research Update by Dr Mark E. S. Bailey (School of Life Sciences) & Dr Stuart R. Cobb (Institute of Neuroscience and Psychology) College of Medical, Veterinary and Life Sciences, University of Glasgow RSAS has awarded £7,000 to Dr Bailey and Dr Cobb for a project over 2 years entitled “Is protein therapy a viable strategy in Rett syndrome?”. The rationale for this project stems from the work already completed in Dr Bailey and Dr Cobb’s laboratories with the support of RSAS. It has been demonstrated that there is an ongoing requirement in brain cells for the MeCP2 protein beyond early development and throughout adult life. It is also clear that if MeCP2 can be provided to the cells of mice lacking the Mecp2 gene (a good genetic model for Rett syndrome), the cells can begin to function normally and the condition of the mouse itself can improve markedly. As Dr Cobb and Prof Bird showed in 2007, this can be achieved in Mecp2 knockout mice by reactivating the gene. This will not work in human RTT patients, however. Dr Bailey and Dr Cobb have more recently shown that supplying the MECP2 gene using a modified viral vector, a form of gene therapy, can also improve the condition of the mice, and they feel that this may be translatable, in time, to a therapy for RTT patients. One of the challenges associated with this approach is delivering the gene to the brain without further damaging cells that are already functioning poorly. An alternative approach might be to deliver the gene to cells of another organ that is not amongst those functioning particularly poorly in patients (e.g. the liver), and have that organ produce molecules of the MeCP2 protein and send them to the brain, where they may be taken up by brain cells and used by those cells - a form of what is called ‘protein replacement therapy’. The current project aims to develop the resources needed to test this question and start investigating whether it looks as though it can work in the knockout mice. As ever, Dr Bailey and Dr Cobb are very grateful for the funding that RSAS has made available to them so far. BOOK – Rett Syndrome: Therapeutic Interventions Those of us who attended the RS Europe meeting in Edinburgh in 2010 were very impressed by a talk given by Meir Lotan on physiotherapy for Rett people. Dr Alison Kerr, who has years of experience with Rett people, has contributed to the book and highly recommends it as being useful to our families. Because of this the Association has kept in touch with Meir and he has advised us that a book which he has helped to produce is now out in a paperback version. RSAS has ordered two copies which will be made available to members to borrow. Our medical adviser, When the book is received it will be reviewed and further details will be given of how it could be useful to you in the upbringing and challenges that you face in your role as parent / carer of a Rett person. Grateful thanks to John and the boys at adprint for all their help. Music Therapy Booklet by Caroline Groves As the Association has run out of the booklet “Music Therapy in the Treatment of Rett Syndrome” and with the importance of music in the lives of our Rett people, the committee decided that a new and updated booklet should be produced. The music therapy day, postponed from last year, took place at St Anne’s Church, Corstorphine, Edinburgh on Thursday 4th April. The therapy sessions were run by Janette Montague, music therapist, with John Slavin, photographer, on hand to capture the moment. Individual music therapy sessions took place and also a group session. This was then followed by lunch, with time for the families and professionals to socialise afterwards. Janette and John will now cooperate to produce the booklet and it is hoped that copies will be available in the autumn. A big thank you is extended to the families / carers, Rett people and professionals who attended on the day. RSAS WEBSITE Rhiannon Thompson has now taken over the running of the RSAS website and has been busy updating it. Please visit www.rettsyndromescotland.co.uk to view the new-look site and let us have your feedback on how you would like to see it develop and if you have anything you would like to add to the site. Annual General Meeting 2013 The AGM took place in the Premier Inn, George St. Glasgow on Sunday 23rd June 2013 Despite difficulties accessing the hotel due to the National Cycling Championships taking place in the surrounding streets, which had been closed to vehicles, all those who wished to attend were able to get through eventually. Due to business commitments Gordon Weir has had to step down from the committee this year, but the Association is grateful to him for his support. Pauline McQuillan has agreed to join the committee and it is hoped that she will be co-opted on at the next meeting. The remaining committee members were re-elected. Accounts The 2012 – 2013 Accounts have now been independently examined and passed to OSCR The Accounts for the year 2012 – 2013 have been independently examined and have been accepted by OSCR (Office of the Scottish Charity Regulator). Further details of the accounts will appear in the next issue of the newsletter. General discussion of the accounts took place at the AGM but will be discussed more fully at the next committee meeting. However, it was pointed out that donations were down by almost 50% from the previous year’s accounts, from £3,451 to £1,761. This could be due to the money raised from the relay, over £4,500, or a sign of the times. The cash and bank balances stood at £59,001, compared with £66,686 the previous year. A very rough estimate of annual income/expenditure was a deficit of £10,000, including funding of research and the cost of the Family Weekend. The committee regularly discusses the budget and continues to agree that both these items are of significant benefit to our families and also uphold the aims of the Association. However, with finite resources and at the current rate of expenditure the Association will only be able to continue in its current form for another five years approximately. This problem continues to raise its head and once again the committee will contact members for their views on the continued existence of the Association in its current form. Meanwhile, if you have any comments that you wish to make to the committee, please contact the secretary. REGIONAL ROADSHOW Rett UK has contacted us to suggest hosting a Regional Roadshow in Scotland in collaboration with RSAS. Weekend at Badaguish. They envisage holding a professional symposium for medical / health professionals. They are chasing funding for the event, but have suggested that perhaps it could coincide with next year’s Family We will keep you informed of progress. Coast to Coast Relay for Rett 2013 and the inaugural Coast to Coast Ultra for Rett 2013 by Caroline Groves, Secretary The team members who took part in this year’s Coast to Coast Relay for Rett 2013 and David McMahon who was the first person to complete the Coast to Coast Ultra for Rett 2013 are to be congratulated on their efforts. Day One, Largs – Bell’s Bridge David McPhee and his girlfriend, Victoria, who last year took part as members of the Bank of Scotland Aspire Team, again made the trek to Largs to start the Relay. David ran and Victoria cycled and both completed the first leg. The weather was glorious, with the sea like a millpond. The pair completed their six mile section at Fencebay, where they handed the baton on to new mum Carina, who carried it up the very steep hill to the Dalry Moor, with its fabulous views across the Firth of Clyde to Arran and the Mull of Kintyre. Here she passed the baton on to her 5 months old baby daughter Caireen and together with granny (RSAS secretary, Caroline) the baton was “buggied” the next short section before Caroline continued by bike into Dalry where the trio paused for a well-earned lunch, before cycling to Lochwinnoch. Our Chairman, Graeme, covered the next 17 miles, walking to Johnston, where he jumped onto the bike and cycled into Glasgow, to complete the first day of the Relay at Bell’s Bridge. Day Three, The Falkirk Wheel – South Queensferry The weather had improved a bit by Sunday morning, although it was still damp and misty. Kate and Angela had continued their holiday on the barge and welcomed aboard the first leg participants. These included their friends John and Susan, Angela’s brother, Richard, his girlfriend, Morag and Caroline. The barge was crewed by Oscar and Brian, volunteers with the Seagull Trust. The barge left the basin at the start of the first leg of this section and was lifted from the Forth and Clyde Canal by the Falkirk Wheel and on to the Union Canal, where Oscar and Brian handed over the navigation to Richard and John, who luckily managed to avoid sinking it! The trip along the canal was wonderful, with some astounding scenery, yet close to built up areas. John and Susan had provided us all with delicious soup and sandwiches and lunch was eaten on board when we had moored at the Seagull Trust Boathouse. From the boathouse Richard took over the baton from Angela and cycled the 17 mile leg into South Queensferry, without mishap (at least nothing he told us about), where he handed the baton on to Muriel. Muriel and Angela, accompanied by Anne, Janet and Kate then walked / wheelchaired to cross the finish line and complete the last leg of the Coast to Coast Relay for Rett 2013. But that’s not the end of it! Day Two, Bell’s Bridge – The Falkirk Wheel Baby Caireen and Carina had volunteered to start the second day of the relay at Bell’s Bridge, but the baby had been unwell so instead Caroline walked that section to Kelvingrove Park. Here she met up with Audrey O’Brien and her friend Chiréne on their bikes. Some of you may remember Audrey as being a carer for Jane Lees at one time. Audrey has stayed in touch and continues to support the Association. The weather on the second day of the relay couldn’t have been more of a contrast to the previous day. It dawned cold, grey and dreich and as the day progressed it got worse, with torrential downpours making cycling on the towpath of the Forth and Clyde Canal treacherous, as the flooding masked the uneven surface underneath. Luckily Audrey and Chiréne managed to avoid cycling into the canal, although they did carry safety ropes just in case. The two girls cycled the complete section from Kelvin Grove Park to the Falkirk Wheel, a distance of about 24 miles. By the time they arrived at the Wheel, wet and cold, the rain had stopped and Kate and Angela welcomed them aboard their holiday barge, which had been specially adapted by the Seagull Trust. Audrey and Chiréne donned plastic bags on their feet and sat on bin bags to avoid soaking everything that they came into contact with. Graeme had already reached the barge and he set-to making hot chocolate with marshmallows all round. The girls had intended to cycle back along the towpath to the start of their section, but it was decided that, due to the adverse weather conditions it would be more sensible for them to get a lift back, so they and their bikes were loaded into the cars for the journey home. Well done to both of them for a sterling effort. Coast to Coast Ultra for Rett 2013 Last year some of the participants who took part in the Relay felt that their section had not been enough of a challenge and had suggested that they would like a greater test of their fitness and endurance. It was decided that this year we should offer entrants the chance to complete either a one-day section of the Relay or the chance to cover the complete 85 + miles. Several people were keen to take up this new challenge but unfortunately the dates didn’t suit, so it fell to David McMahon to be the first person to participate in the inaugural Coast to Coast Ultra for Rett. Unfortunately for David he chose the worst day weather-wise to take up the challenge and set off on Saturday 18th May from Largs. Apart from getting lost in Glasgow, having problems with the surface water on the towpath and suffering from near hypothermia, David managed to safely complete the whole distance in one day to receive the first ever Ultra medal. What a tremendous achievement. An enormous thank-you goes to those who took part and to those who have sponsored the participants. Special thanks go to D Mackay, Manager of Timpson, Largs, who acted as starter for the Ultra and also to Fencebay Smokery for allowing us the use of their car park as a changeover point. Also to Kate and Angela for allowing us to use their holiday barge when the original Seagull Trust barge was out of action. SPONSORSHIP MONEY FOR THE RELAY HAS NOW REACHED £500 WITH MORE TO COME! DAY 1 Largs to Bell’s Bridge Carina, David, Victoria and Caireen at the changeover at Fencebay Car Park. Carina arrives at the summit of the Dalry Moor… …and hands the baton to Caireen for the next leg. DAY 2 Bell’s Bridge to the Falkirk Wheel Graeme, Chiréne and Audrey, sheltering from the rain at the canalside, Twechar. The brave duo arrive at the end of the stage at the Falkirk Wheel. Drying out on the barge (note the polybags on the feet and the bags on the settee) with Angela, whilst Graeme makes hot chocolate with marshmallows in the galley.

Whilst abseilers descend from the bridge, Richard, Morag, John, Angela and Kate wear their relay medals and David wears the first ever Ultra medal. Last year, following committee discussions, it was agreed that membership of RS Europe would be of great benefit to our Association in its stated intentions “to work with other organisations to secure the best interests of children and adults with Rett Syndrome and their families.” It was therefore decided that RSAS should become a member of RSE, with its connections to Eurordis and Rare Connect. Chairman, Graeme Dallachy, therefore attended the General Assembly of Rett Syndrome Europe in London in November 2012 as representative of RSAS. Twenty other representatives attended together with researchers Angus Clarke and Laurent Villard, both of whom addressed the meeting. The summary of Laurent Villard’s report is shown below. Rett Syndrome: What’s Up? Rett Syndrome Europe General Assembly - London, 17th November 2012 The presentation was divided in 3 sections dealing with basic research, translational research and networks/meetings. by Laurent Villard, PhD I - BASIC RESEARCH 1. MECP2 IS GOING GLOBAL The understanding of what is Mecp2 really doing inside the brain cells is rapidly evolving. Initially, Mecp2 was thought to repress (and possibly activate) transcription at the gene level through binding to methylated elements in the vicinity of a small subset of target genes. Currently, based on the work of the laboratory of Adrian Bird (UK), MEPC2 is rather believed to regulate the expression of thousands of gene, genome wide. Indeed, it was calculated that the MECP2 protein was abundant enough in the nerve cells to replace histone H1, a protein that structures the DNA molecule globally. Hence, rather than regulating the expression of a selected subset of genes, MEPC2 is now thought to regulate the whole DNA molecule in neuronal cells. This regulation of gene expression inside each cell is of paramout importance because cells need specific sets of genes to be expressed in order to achieve its development and function. Obviously, a sperm cell and a neuron need different proteins to be built, although their DNA is identical. This differential expression of proteins is made possible through proteins such as MECP2, among others. 2. MEC2 MAINTAINS MATURE NEURONAL NETWORKS The group of Nurit Ballas (USA) recently described that the loss of MECP2 in the adult stage of the disease (in the mouse) was causing brain shrinking. The dendritic arborization (contacts of neuronal cells with neighbouring cells) becomes less complex. This finding suggests that MECP2 is necessary to maintain mature neuronal networks and reinforces the notion that the protein is not necessary during the development but rather, is necessary when neurons reach their final differentiation stage. 3. WILD TYPE MICROGLIA ARREST RETT SYNDROME. This is the recent work of Jonathan Kipnis (USA). Glial cells are "maintenance" cells in the nervous system. They insulate neuronal connections (oligodendrocytes), feed neurons (astrocytes) or clean debris (microglia) among other functions. A significant amount of data supports the idea that glial cells, in addition to neurons, play a role in RTT. Indeed, MECP2-deficient astrocytes cannot support normal growth of wild type neurones; the rescue of MECP2 in astrocytes improves the disease phenotype and MECP2 deficient microglial cells were shown to be toxic to neurones. Microglia are the macrophages of the brain. They originate from bone marrow. Jonathan Kipnis and his colleagues suppressed immunity in RTT mice and subsequently injected wild type bone marrow (intravenously). Wild type microglia were detected in the brain of the injected animals after a period of time. The lifespan of the grafted animals rose from 8 to 44 weeks of age, their brain size increased and their growth was normalized within 4 weeks of transplantation. Tremors were suppressed by transplantation, gait, motor and breathing abilities were also improved. A similar improvement was observed for treated RTT female mice. However, late transplantation (i.e. when the disease in installed) only results in modest improvements. Why such an effect of microglia? A diffusion of MECP2 between wild type microglia and disease neurons was ruled out. Rather, is it proposed that wild type microglia could better sustain growth factor secretion (e.g. IGF-1) or allow a better clearance of (physiological) debris. 4. MECP2 CANNOT COMPENSATE ALL MUTATIONS. The phenotype of the MECP2-null mouse (no MECP2 protein produced) can be rescued by post-symptomatic activation of MECP2 (work of Adrian Bird and others). However, a large proportion of RTT girls are not complete nulls and have missense or other types of mutations possibly allowing the presence of an abnormal MECP2 protein. A study reported as a poster at the annual meeting of the American Society of Human Genetics (ASHG november 2012) by Juan YOUNG (Miami, USA) reports that there is no improvement of the phenotype when MECP2 is introduced in a non-null context (a mouse harbouring a truncating mutation). According to this work, there is a possibility that mutant MECP2 protein interferes with wild type protein and prevents reversal of the phenotype. 5. A RAT MODEL FOR RETT SYNDROME. The SAGE initiative (Sigma advanced genetic engineering) reported the creation of a rat model of RTT. The RTT rats are completely devoid of MECP2 protein. These animals are being sold by SIGMA. The advantage of the rat above the mouse is that this model is much more suitable for social and behavioral exploration, its brain can be studied more easily with electrophysiology devices and it lives longer than a mouse. II - TRANSLATIONAL RESEARCH 1. OUTCOME MEASURES Valid outcome measures are needed for RTT clinical trials. Two interesting options were discussed at the World Rett Syndrome conference (june 2012, New Orleans). Infrared monitoring (F. Symons, USA) Body temperature is usually identical on both sides of the body. A study performed on 5 RTT patients showed body temperature asymetry (in hands and feet, up to 10°C difference). This non invasive measurement could be used to measure efficacy of treatments targeting the autonomic nervous system. Pupillometry (PP. Patwari, USA) Pupillary contraction is controlled by the autonomous nervous system. Its measure is non invasive, quantitative and rapid. It is used in Ondine’s disease and proposed to be used in RTT. RettBe (W. Kaufmann, USA) RettBe is an initiative aiming at developing a behavioral rating scale for children affected by RTT (3 to 18 years). The cohort size will be 350 patients The rating scale will be distributed to the RTT community at large. 2. ONGOING TRIALS IGF-1 (Boston, MA, USA) Information lacking... (a new PI is in charge). A group in Houston (J. Neul) reported that a modified version of IGF-1 (supposed to be improved) at no effect at low dose and was worsening the disease at high dose. Desipramine (France, 6 centers) 32 patients have been included in a total of 36 patients. Since it is a double blind trial, results will not be available until all participants have been treated (the trial length for each girl is 8 months). 3. ACTIVATION OF THE BDNF RECEPTOR WITH DHF BDNF is deficient in the RTT mouse. Increasing BDNF levels in the RTT mouse improves the disease. BDNF itself does not reach the brain very efficiently and cannot be used directly. DHF (dihydroxyflavone) supposedly activates the BDNF receptor. It is a new molecule. Contradictory results were obtained in different groups with positive (Johnson et al. 2012) and negative (Villard, Roux, unpublished and RSRT, personal communication) results. 4. BDNF TRAFFICKING AND CYSTEAMINE BDNF is an important growth factor necessary for neuronal function. BDNF is regulated by Mecp2 and is deficient in the "RTT" mouse. HTT (the product of the huntington's disease gene) regulates BDNF trafficking in the axons. The group of Marseille (L Villard / JC Roux) showed that HTT was deficient in the RTT mouse. Cysteamine improves BDNF trafficking and delivery. It is used on clinical trials with Huntington's disease patients. Data from the french group shows that cysteamine improves the phenotype of the Mecp2-deficient mouse. 5. GENE THERAPY Most gene therapy protocols now use adeno-associated viruses (AAV) as a vector to deliver the gene therapy agent inside the cells. AAVs do not cause disease, they infect dividing and non-dividing cells and they do not integrate. The group of Stuart Cobb recently reported that AAVs can be useful to treat MECP2 deficient mice. The used the AAV9 serotype, containing MECP2 and injected into MECP2-null neonatal mice (intracranial). Median survival of the treated animals was 16.6 weeks instead of 9.3 weeks for untreated animals. Locomotor function, exploratory activity and neuronal volume were all significantly improved. Breathing deficits were not improved, however. Later on, when the treatment is performed at 4-5 weesks of age, the effect is much more modest. The issue is likely to be efficient delivery of the vector to the nerve cells. III - NETWORKS - MEETINGS EuroRETT funding is over but the group is still active. There is one major achievement to maintain: the database (cf. Angus Clarke presentation at the meeting). A group of RTT clinicians was also built, independently from EuroRETT, called ESSRA. There is no connection to EuroRETT (despite several requests) and no participation to the european database (despite several requests). Concerning meetings, the next RTT european conference will be held in Maastricht (NL) in October 2013 and the next World Congress could be held in Moscow in 2016.

Further information can be obtained by accessing: www.eurordis.org FORTHCOMING EVENTS Badaguish Family Weekend Friday 9th August – Monday 12th August 2013 At present we have eight families attending this fun event, which offers archery, canoeing, abseiling and cycling using specially adapted equipment and supervised by professionals. We are also hoping that there will be other activities taking place over the weekend. Accommodation is in luxurious, adapted lodges and catering has been organized. If you think you might be interested in attending please contact the secretary as soon as possible. Rock the Rovers Sunday August 25th 2013 Rock the Rovers is an annual music festival held in Kirkcaldy and organized by supporters of Raith Rovers Football Club to raise money for local charities and the football club. Founded in 2005 the event has earned a reputation as being the number 1 music event in Fife, with bands from all over the country – and some even further – playing at the one day event. TICKETS FOR ROCK THE ROVERS ARE NOW ON SALE, PRICED £10. There will be 20 acts playing on two stages at KITTYS and KANDY in Kirkcaldy throughout the day of Sunday August 25th. A friend of one of the organizers has a Rett daughter and so one of the chosen charities of this year’s event is to be Rett Syndrome Association Scotland. It is hoped that a cheque for £500 will be presented to RSAS in September.

European Rett Syndrome Conference Maastricht, The Netherlands 17th – 19th October 2013 This year the conference “Research Update and Preventative Management” is taking place in Maastricht. The main goal of this conference is to bring together a group of world-class scientists, researchers, clinicians, practitioners and stimulate multi-disciplinary international cooperation. The aim is to also provide therapists, parents and caretakers with a toolbox that includes the latest information on treatment of symptoms. General topics: Treatment and clinical management Adult Rett and Ageing in Rett syndrome Family education and awareness Genetics and Neurobiology Brain and brainstem physiology Sleep Cognition & Communication Nutrition Orthopaedic Moving research into policy and practice Rare disease initiatives in Europe and overseas Case studies MECP2 duplication, FOXG1, CDKL-5, etc The conference in London 2012 was considered to be very worthwhile and it is hoped that a representative from RSAS will be able to attend this year’s event.

Many thanks to Joan for organising it this year and to everyone who came along and helped on the day and to those who donated items and / or bought goodies from us. A total of £333 was raised for Rett Syndrome Association Scotland Thanks must also go to two “knights in shining armour”, who went to the aid of the secretary on her way to the Fayre, when her car (containing stock for the stall) broke down. Frances Binnie, flanked by her daughter, Alison and granddaughter, Nicola, together with Joan and Jacqui. Firstly, the gentleman from Highfield Heavies who diagnosed the problem and was able to make a temporary repair enabling her to drive to Glasgow and also Graham Steadman, General Manager of M8 Recovery, who personally drove her and the stock to the railway station to enable her to deliver it to the Fayre and then collected her from the station to return her to her car.
