Louise Daugherty (Genomics England Curator)

As a result of watchlist tag audit the watchlist tag was removed from JPH2- this is now a green gene with sufficient evidence/review

Kate Thomson (Oxford University Hospitals Foundation Trust)

Green List (high evidence)

Submitted on behalf of the GMS Cardiology specialist group. This gene did not achieve a consensus Green rating; however, the group agreed that the existing evidence (published and in-house data) was sufficient to support inclusion in this panel.

Cardiomyopathy, hypertrophic, 17 (605267 )
Created: 25 Mar 2019, 4:30 p.m.
Weak evidence for primary role in pathogenicity: 28082330. Insufficient evidence, no supporting segregation, despite functional assays. PMID: 28393127 - a novel variant identified in a proband with significant basal septal hypertrophy. Neither parents were genotyped. his mutation was absent in 159,358 reference alleles. Variants in in MYH7, MYBPC3, MYL2, MYL3, TTNT2, TTNI3, TNNC1, TPM1, ACTC, PRKAG2, GLA, and LAMP2 genes, were excluded in this patient. Mice with this variant exhibit similar basal hypertrophy using a newly developed echo imaging plane, and this was confirmed using cardiac MRI. Histological analysis demonstrated cardiomyocyte hypertrophy and disarray consistent with HCM. 3 additional missense variants reported in 3 cases in PMID: 17509612 (2007), however another missense variant Gly550Ser in this gene has been reclassified as unknown pathogenic significance, due to presence in allele frequency databases. HGMD: 8 DM variants - 3 DCM rest HCM. Functional studies shown an effect in JPH2 but no variants with evidence of segregation. 10.1093/eurheartj/ehw603

This gene was part of an initial gene list collated by Matthew Edwards Royal Brompton Hospital sent 16th Jan 2019 on behalf of the London South GLH for review by the GMS Cardiology Specialist Group. Only gene symbol from the Royal Brompton gene panel was provided - suggested initial gene rating and evidence for inclusion not provided with the list.
