Invitae RCV001223140 SCV001395275 uncertain significance Danon disease 2019-07-15 criteria provided, single submitter clinical testing 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 tolerated, 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 LAMP2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with serine at codon 156 of the LAMP2 protein (p.Leu156Ser). The leucine residue is weakly conserved and there is a large physicochemical difference between leucine and serine.
GeneDx RCV003129739 SCV003805975 uncertain significance not provided 2022-08-15 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function
