NHS ill- prepared Sub-committees to identify educational needs www.geneticseducation.nhs.uk Equitable delivery of high quality integrated pathways
Molecular test Family management Patient management
Management could mean :- • Diagnosis • Patient Treatment (personalised medicine) • Pre-symptomatic testing • Surveillance Maximise to obtain most clinical benefit and utility
Molecular test Family management Patient management
What are we trying to achieve?Optimisation of each of the Steps
What are we trying to achieve?Optimisation of each of the Steps and Extended family engagement where appropriate
Access success – simple!! (If only) • Educated and engaged public • More aware profession and easier access to pathways (know when to refer) • Commissioning process that encourages early intervention for the “well” – primary and secondary care
Illustration of Diagnostic Process Deliberations and Consequences :- Is it? • Marfan syndrome • Rare aortopathy • Homocysteinuria
How to encourage most appropriate diagnostic process :– make it part of a required pathway • Homocysteinuria – urine adequate only if no other management issues • Marfans – is a clinical diagnosis adequate to answer “all the other medical issues” to the benefit of “the whole NHS” • Rare aortopathy – do I need to be aware of these alternative diagnoses and management issues
Use SCN and NHSCB through CRG to :- • Promote commissioning of MDT working • Optimise pathway • Support most appropriate clinical involvement (egMarfans – expert cardiology, cardiothoracic surgeons, ophthalmology, clinical geneticists, nurse specialist/ genetic counsellors, orthopaedics, physiotherapy etc)
What are we trying to achieve?Optimisation of each of the Steps and Extended family engagement where appropriate
For “each patient” MDT discussion or agreed protocols to consider appropriate :- • Diagnosis (What do I need to achieve 2 &3) • Management • Genetic Cascade • “premium for care” in “quality assured pathways” to cover initial expenses but to ensure downstream benefits (central to UKGTN gene dossiers – link from NLMC)
Engagement of Public and Professionals(Requirement of the quality assured pathway) • HGSG – importance of engagement and education • GMC – medical school requirement • Royal Colleges and NMC – JCMG report • HEE – ensure part of the “CPD curriculum” for LETB’s – remove the “unknown unknowns” • Member of NCB with remit to genomics and promotion of education across the NHS • Commissioners only support “QAP”
Encourage engagement of Pharma and Biotechnology • Smaller number of collaborators for more patients enrolled • More consistent cohorts • More consistent evaluations • More cost effective research
More consistency of consent • More consistency of consent process • Increased awareness of equivocal results and interpretation • Greater support for interpretation of equivocal results • Greater emphasis on sharing information for knowledge and family management as norm rather than exception or retrospective
Should not be “a charter for ivory towers” practice : Criteria should be QAP delivery • Rare is common – 3 million people in England have a rare disorder. • 80% genetic • Many multisystem But many • Common enough to be managed in many centres (1 versus >1 per “sector”) • Need a lot of local support and input – horizontal integrated care with IT systems to share relevant data and protocol management

Geleophysic – Acromicric DysplasiaNeed to overcome - “Who pays for the test?” • Geleophysic – AR due to mutations in ADAMTLS2 gene • Geleophysic/Acromicric – AD due to mutations in the fibrillin gene • Prognosis differs across spectrum • Fibrillin mutation disorders show evidence of response to anti TGF therapy • Recurrence risk 1 in 2, 1 in 4 or very low
Multiple Endocrine Neoplasia type 2 (MEN 2) • MEN 2A MTC Phaeochromocytoma Hyperparathyroidism • MEN 2B MTC Phaeochromocytoma Marfanoid habitus Mucosal neuroma Ganglioneuromatosis gut • Familial MTC ≥4 MTC No phaeochromocytoma No hyperparathyroidism
Joint MTC at QEH 19 apparently sporadic MTC presenting to QEH over 2 years A mutation was identified in 3/19 (15.8%) V804M heterozygous 43y male V804M homozygous 54y female C618S heterozygous 30y female Subsequent cascade testing in at risk family members • → 18 predictive genetic tests → 13 positive→ 11 prophylactic thyroidectomies
Joint MTC at QEH • MTC identified in 5 /11 (~45.5%) at prophylactic surgeryC618S familyV804M families53y female 65y female 40y female36y female29y female
Indications for using DNA testing :-genetic management • Cascade screening • Prevention of unnecessary intervention • Appropriate surveillance for at risk individuals • Is presymptomatic diagnosis and intervention going to change the outcome? • Does knowing the genetic basis change the management – (Germline) Warfarin dosage, PARP inhibitors, PTC124. (Somatic - oncology) Herceptin, Gleevac and Iressa
Renal Failure Heart Disease Hypertension Osteoporosis Diabetes Melitus Most Types of Cancer All can be single gene or multifactorial All amenable to intervention Surveillance is often very simple Genetic testing maybe difficult and expensive Taking a family history is very easy and cheap! Some genetic testing is very beneficial Common Disease with a Major Genetic Component
Indications for genetic testingor (How to persuade your commissioners!) • Diagnosis (avoidance of unnecessary investigations) • Management (most appropriate follow up and treatment) • Genetic follow up (identification of gene carriers and exclusion of population risk follow up) • Ensure you get the maximum clinical utility from you test (a no brainer???)
