Labcorp Genetics (formerly Invitae), Labcorp RCV001321189 SCV001512008 uncertain significance Bloom syndrome 2023-10-26 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with arginine, which is basic and polar, at codon 81 of the BLM protein (p.Thr81Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BLM-related conditions. ClinVar contains an entry for this variant (Variation ID: 1021427). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.
