Labcorp Genetics (formerly Invitae), Labcorp RCV000544576 SCV000623295 uncertain significance Bloom syndrome 2017-05-24 criteria provided, single submitter clinical testing This sequence change replaces cysteine with arginine at codon 989 of the BLM protein (p.Cys989Arg). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with a BLM-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant has uncertain impact on BLM function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
