Comment on list classification: Due to new expert reviews and disputed evidence for this gene-disease causation, this gene has been demoted from Green to Red.Created: 27 Feb 2019, 9:59 a.m.
This gene was given a validity classification of Disputed by the ClinGen validity curation group and is reflected by providing a Red review here.The gene-disease summary was downloaded on 20th Feb 2019.For the full report and publications see the ClinGen Gene Validity Curation for each gene here: https://search.clinicalgenome.org/kb/gene-validity/10152Created: 20 Feb 2019, 2:47 p.m.
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.Created: 20 Feb 2019, 2:17 p.m.

Comment when marking as ready: On Manchester diagnostic panel; Multiple unrelated patients in OMIM; Some functional evidenceCreated: 11 Feb 2016, 11:18 a.m.
Variants detected in individuals with 2 different phenotypes - Brugada syndrome and periodic paralysis. Abbot et al report expression at low levels in the heart. 2 variants reported: T4A which we would consider unlikely / polymorphism (0.4 percentage of East Asians on gnomAD). R99H - which has conflicting interpretations on ClinVar (unlikely UV likely and pathogenic). Could be a potential candidate gene but zero evidence at present.Created: 25 Jan 2019, 1:15 p.m.
