Diagnosis
•
•
109 recommendations
all based on assessing published evidence
All individuals should be offered a DNA test to confirm the
diagnosis and to assist in Cascade testing of relatives
Issue date
In children at risk of FH (one affected parent) the following
: August 2008
Identification and
management of familial
hypercholesterolaemia
diagnostic tests should be carried out by age of 10 years :
- a DNA test if the family mutation is known
- LDL-C measurement if mutation not known

Identifying people with FH using cascade testing
•
Cascade testing - combination of DNA testing and LDL-C levels is recommended
to identify affected relatives of those with a clinical FH.
Knowing the family mutation is a key piece of information for cascade
testing and for starting statin therapy in childhood.

Adults with a baseline total cholesterol above 7.5mmol/l are assessed for a clinical
diagnosis of FH
People with a clinical diagnosis of FH are referred to a specialist with expertise in FH.
People with a clinical diagnosis of FH are offered DNA testing.
Children at risk of FH are offered diagnostic tests by the age of 10 years.
Relatives of people with a confirmed diagnosis of FH are offered testing through a
nationwide, systematic cascade process.
Adults with FH receive lipid-modifying drug treatment to reduce LDL-C concentration by
more than 50% from baseline.
Children with FH are offered lipid-modifying drug treatment by a healthcare professional
with expertise in FH in a child-focused setting by the age of 10 years.
People with FH are offered a structured review at least annually.
Knowing the family mutation is a key piece of information for cascade
testing and for starting statin therapy in childhood.
How Common is FH ?
• It is Common - Frequency FH ~1/500

First in world
Up until now costs ~£5-600 and takes 2-4 months
Test of single mutation in relative ~ £70.
Cholesterol test ~£10, ECG ~£300
Have now developed Next Generation Sequencing methods
which allow all the FH genes to be sequenced in one go !
and soon  96 samples to be analysed in one run!
Cost falling to under £250!!!

DNA testing gives an unambiguous result
What is overall mutation detection rate?
Taylor et al Clin Genet 2010
100 patients with a clinical diagnosis of FH
(DFH+PFH or DLCN score > 3)
66 with PFH
34 with DFH
(DLCN score > 3)
(DLCN score > 8)
Detection rate 20-30%
Detection rate 70-80%
Mutation in 13-20
Mutation in 24-27
Overall find a monogenic molecular cause in 35-47% of patients
No mutation patients?
Detection Rate of ~80% in DFH patients compares favourably with the 20-30%
seen in BRCAI/2 in familial breast cancer- also fewer “unclassified” variants

Technical reasons – No method detects all mutations.
Sequencing introns may find > mutations

Genetic heterogeneity – May be 4th or 5th gene to be found.
Predict prevalence < PCSK9 ie < 2%

Over-Diagnosis – Many patients do not have “true” FH. Family
history of hypercholesterolaemia and early CHD not very specific.
Many have polygenic cause
Polygenic Cause of no mutation FH
Talmud et al Lancet 2013
Hypothesis
Having a large number of common genetic variants that each
raise LDL-C by a small amount could mimic Monogenic FH



Used 12 common variants (SNPs) in 321 Mutation negative FH patients
from UK, 451 from Belgium and compared with 3000 healthy men and
women from the Whitehall II Study
Results in UK non mutation FH patients show that in at least 80% a
“polygenic” cause of their elevated LDL-C is most likely explanation
Results confirmed in Belgium patients and now in samples from 6
other countries - Futema et al Clin Chem in press
Why is the polygenic explanation important?
•
•
•
•
Research: Searching for a monogenic cause of FH in high
score patients will not be successful!!!
Money : 2008 NICE Guideline CG71 Cascade testing should be
done in all patients with a clinical diagnosis of FH using DNA
where available and LDL-C where not.
But Cascade testing those with polygenic hypercholesterolemia
 much less cost effective – fewer than 30% “affected” relatives
Treatment : Predict polygenic patients will have less severe
disease and can be easily managed by statin treatment in
general practice (not expensive tertiary referral centres)
Important for FH Guidelines and we are testing these hypotheses
NICE, Children and statins
•
•
There are 7,000,000 children <10years in UK.
Predict 14, 000 FH children
Roughly 7,000,000 between 10-18 years in UK.
Predict 14,000 FH Teenageers
At most 600 currently known !
- HEARTUK Survey Jan 2008, UK FH Audit 2010
NICE CG71 Recommendation
Lipid-modifying drug therapy for a child or young person with FH should
usually be considered by the age of 10 years.
What is Evidence to support this recommendation?

Aims :
 To collect SB-type information on all identified FH children in UK
 To update information annually wrt growth/statin use/side effects etc
Clinicians still reluctant to prescribe statins in case of some long term risk
 Reduce loss to follow up as children  adult clinics
 Steering group of clinicians, Colleges, charities and patient reps

Adult specialist lipid clinics well established in 6 Trusts
– Durham, Gateshead, Hartlepool, Newcastle, Northumbria, Sunderland
Adult FH patients also seen in outpatients in Carlisle, Middlesbrough
Paediatric Lipid clinics in 2 Trusts
– Newcastle and Sunderland, both signed up for RCP National Paediatric FH Register
Regional experience of FH Genetic Diagnosis and Family Cascade Testing
- Newcastle Clinic and Regional Genetics participated in National Pilot Study of FH Genetic Diagnosis
and Family Cascade Testing 2005-2008, 145 probands genotyped
Regional Genetic Service agree to continue support for FH mutation testing
- continue to accept requests for of relatives of FH probands with known mutations.
Specialist Lipid Clinics Network created in 2008
- agreed NICE CG71 compliant FH identification and management pathway
NECVN Lipid Specialists Advisory Group (LSAG) established 2009
NECVN endorsed proposal for Implementation of NICE CG71
- rejected by commissioners 2009, 2010
FATS Primary Care Guidelines for Identification of FH
- developed, promoted and implemented in Newcastle and Northumbria 2009
FATS Primary Care Guidelines for Identification of FH
- adopted by NECVN but not widely promoted not yet fully implemented
NECVN Standards for identification of FH in Acute Cardiology patients
- developed by LSAG, launched Jan 2013
Key Findings from the RCP FH Audit
The clinical management in lipid clinics is of a good standard for
individual patients who have been diagnosed with FH.
Current resources are inadequate to cope with the identification of the
predicted additional FH cases UK wide.
There is a major lack of family “cascade” testing, whether carried out
on the basis of lipid levels, or more effectively by a DNA diagnosis.
While there is good access to DNA diagnosis and funding for DNA
testing in the Devolved Provinces, access and funding in England is
poor.
There is a shortfall in child-focused services throughout the country,
with only 26% of sites offering paediatric FH services.
FH Services in the North East – Gap Analysis
• No centralised disease register for Adult FH probands and families in
North East
• No Specialist nurses in Adult or Paediatric FH Clinics
• No regional infrastructure for FH Family cascade testing available to
support Clinics
• No access to DNA mutation testing for new FH probands
• No clinical management database software (e.g. PASS) available to FH
Clinics
• Adult specialist lipid clinics capacity shortfall, particularly in the south of
the Region
• Paediatric Lipid clinics not available in south of the Region
• FATS/NECVN Primary Care FH Guidelines not fully implemented in
south of Region
• No access to LDL Apheresis

or early CVD: GP assesses if patient meets SC referral criteria 1(clinical
examination and exclusion of secondary causes of hyperlipidaemia) 2 full fasting
lipid profiles ( 3 months apart)
Secondary care specialist identifies patient
meets SC referral criteria
GP CVD assessment & commencement of statins2 (using secondary care
protocols and lipid clinic advice); offer primary/secondary prevention

Conclusions
• Working well in Wales to support a nationwide,
systematic cascade testing service.
• Ability to link up all FH services in England to
allow cascade testing of families spread out
geographically.
• Allows FH services to be evaluated and audited.
• I have been supporting the implementation of
PASS in England and will continue to do so.

Interpretation and alerting


Interpretative commenting was associated
with a significant additional LDL-c reduction
and increased specialist referrals compared
with controls.
However, only a minority of individuals
received a specialist referral.

Questions and discussion
BHF FH funding criteria
Professor Peter Weissberg, BHF
Medical Director
Supporting FH Cascade
Testing Services
BHF Funding November 2014
Funding available
• BHF will fund FH nurses salaries and
admin staff provide the need for the latter
is clear
• 100% salary in year 1 and 50% salary in
year 2
• Approximately £100K to £150K per trust
Funding will not be
available for:
• Genetic testing
• PASS software
• Any additional running costs for the
service
Key Points
• There must be a named lead clinician
• There must be a named paediatrician
• You must commit to delivering an FH
cascade testing service:
– Target family members of known index cases
– Identify new index cases
Key Points
• You must have secured funding for the
genetic tests before the funding for the
nurse(s) will be released by BHF
• You must commission genetic tests from
an accredited laboratory where nextgeneration sequencing technologies are
used
Guidance notes
• Please read the guidance notes (sent by
email to each applicant) carefully before
you commence the application process
