Labcorp Genetics (formerly Invitae), Labcorp RCV001206197 SCV001377494 uncertain significance Bloom syndrome 2021-09-14 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: "Probably Damaging"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals affected with BLM-related conditions. This sequence change replaces lysine with methionine at codon 1153 of the BLM protein (p.Lys1153Met). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and methionine. This variant is not present in population databases (ExAC no frequency).
