Invitae RCV001996592 SCV002218907 uncertain significance Myofibrillar myopathy 3 2021-06-28 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 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 MYOT-related conditions. This variant is present in population databases (rs781052225, ExAC 0.02%). This sequence change replaces glutamic acid with alanine at codon 494 of the MYOT protein (p.Glu494Ala). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and alanine.
