Labcorp Genetics (formerly Invitae), Labcorp RCV001324499 SCV001515453 uncertain significance Ullrich congenital muscular dystrophy 2; Bethlem myopathy 2 2020-01-21 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This sequence change replaces tyrosine with histidine at codon 197 of the COL12A1 protein (p.Tyr197His). The tyrosine residue is moderately conserved and there is a moderate physicochemical difference between tyrosine and histidine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with COL12A1-related conditions. 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.
