Comment when marking as ready: Confirmed in the NHSE GMS Cardiology Specialist Group meeting call on 25th January 2019 that this gene should be Green.
Created: 4 Mar 2019, 9:15 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.

James Eden (Manchester)

Green List (high evidence)

Gene currently tested by alternative panel, very few short QT referrals to date. 643 variants listed on HGMD (accessed 29/01/2019). ClinGen Knowledge Base: currently no association with Short QT syndrome, definitive association with Jervell and Lange-Nielsen syndrome, association with long QT syndrome 1 (accessed 29/01/2019).
Created: 14 Feb 2019, 1:38 p.m.

Mode of inheritance
BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal

Phenotypes
Long QT syndrome-1 (192500); Short QT syndrome 2 (609621); Jervell and Lange-Nielsen syndrome (220400); Atrial fibrillation, familial, 3 (607554)

Olivia Niblock (Genomics England Curator)

I don't know

This has been added as part of a test of the new version of PanelApp. However, variants in this gene do appear to be linked to Short QT-interval Syndrome 2, from the cases (5 individuals) described in OMIM. More literature mining is needed.
