Labcorp Genetics (formerly Invitae), Labcorp RCV001362246 SCV001558254 uncertain significance Myofibrillar myopathy 3 2020-02-17 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 MYOT-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with asparagine at codon 339 of the MYOT protein (p.Asp339Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine.
