Invitae RCV000537273 SCV000648292 uncertain significance Congenital muscular dystrophy due to integrin alpha-7 deficiency 2016-12-24 criteria provided, single submitter clinical testing 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. 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. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a ITGA7-related disease. This sequence change replaces isoleucine with lysine at codon 338 of the ITGA7 protein (p.Ile338Lys). The isoleucine residue is moderately conserved and there is a moderate physicochemical difference between isoleucine and lysine.
