Matthew Edwards (Clinical Genetics & Genomics Lab, Royal Brompton & Harefield NHS Trust)

Green List (high evidence)

On CGGL Royal Brompton FTAAD panel. Only VUS reported so far. Good evidence for association with aortic aneurysm in PMID: 16729972 and 26820064 (listed as limited evidence by ClinGen). Pathogenic variants also cause isolated BAV, and congenital cardiac defects via Adam-Oliver syndrome.

Multiple variants classified pathogenic/likely pathogenic using ACMG criteria and gnomAD population data using criteria which appear to be stringent. Southgate et al 2015 Circ Cardiovasc Genet 8:572 PMID:25963545 show segregation of NOTCH1 variants in 4 families and de-novo in 3 families and reduction of mRNA levels implying NMD. Both publications list cardiac phenotypes including BAV, co-arctation of the aorta, aortic regurgitation, aortic stenosis and VSD.

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.

On the Inherited Cardiac Condition Genes panel reported in: Development of a Comprehensive Sequencing Assay for Inherited Cardiac Condition Genes, Pua et al, Journal of Cardiovascular Translational Research, online Feb 2016 (doi:10.​1007/​s12265-016-9673-5). The panel contains disease-causing, putatively pathogenic, research and phenocopy genes, and it is unclear from the publication whether this gene falls into the disease-causing category. One mutation is indicated in the supplemental table in this gene.

Comment when marking as ready: 1 reviewer marked green. Promoted as ready due to significant association with familial bicuspid aortic valve disease and concomitant thoracic aortic aneurysm formation.
Created: 2 Feb 2016, 2:40 p.m.
Comment on publications: Bicuspid aortic valve (BAV) disease association with familial thoracic aortic aneurysm (TAA)- two entities considered as disease spectrum of a common developmental defect. NOTCH1 mutations found in familial calcific BAV disease with concomitant TAA.
