Invitae RCV000809604 SCV000949764 uncertain significance Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A, 7; Autosomal recessive limb-girdle muscular dystrophy type 2U 2019-05-09 criteria provided, single submitter clinical testing This sequence change replaces glutamine with lysine at codon 215 of the ISPD protein (p.Gln215Lys). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and lysine. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, 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 and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ISPD-related disease. This variant is not present in population databases (ExAC no frequency).
