Short QT syndrome
Gene: SCN10A
Gene currently tested by alternative panel, very few short QT referrals to date. Only class 1-3 variants detected in this gene. 85 variants listed on HGMD (accessed 29/01/2019). ClinGen Knowledge Base: disputed association with Brugada syndrome (accessed 29/01/2019).Created: 14 Feb 2019, 1:38 p.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Phenotypes
Episodic pain syndrome, familial, 2 (615551)
Publications
Variants in this GENE are reported as part of current diagnostic practice
This is a very recent report. The evidence that the index patient had short QT is high. Causality is inferred rather than demonstrated functionally through cellular electrophysiology.
There is growing evidence for role of SCN10A in heart
Despite the rating, I would recommend including this on the gene panel as the SQTS is rare and has a low success rate with targeted genotyping. It is possible that the association with SCN10A is stronger and so inclusion would be prudent
