Invitae RCV000536030 SCV000648458 uncertain significance Brugada syndrome 8 2018-10-25 criteria provided, single submitter clinical testing This sequence change replaces alanine with threonine at codon 1088 of the HCN4 protein (p.Ala1088Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a HCN4-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
