Labcorp Genetics (formerly Invitae), Labcorp RCV001930447 SCV002190245 uncertain significance Bloom syndrome 2021-08-26 criteria provided, single submitter clinical testing This sequence change replaces valine with phenylalanine at codon 4 of the BLM protein (p.Val4Phe). The valine residue is weakly conserved and there is a small physicochemical difference between valine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with BLM-related conditions. 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.
