Genes affected

STAC3 (HGNC:28423): (SH3 and cysteine rich domain 3) The protein encoded by this gene is a component of the excitation-contraction coupling machinery of muscles. This protein is a member of the Stac gene family and contains an N-terminal cysteine-rich domain and two SH3 domains. Mutations in this gene are a cause of Native American myopathy.

This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 84 of the STAC3 protein (p.Leu84Arg). This variant is present in population databases (rs201754072, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with STAC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 534099). 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. 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. -
