Labcorp Genetics (formerly Invitae), Labcorp RCV001980966 SCV002281587 uncertain significance Bloom syndrome 2020-12-09 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: "Tolerated"; PolyPhen-2: "Possibly 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 with BLM-related conditions. This sequence change replaces aspartic acid with valine at codon 1156 of the BLM protein (p.Asp1156Val). The aspartic acid residue is moderately conserved and there is a large physicochemical difference between aspartic acid and valine. This variant is not present in population databases (ExAC no frequency).
