Ambry Genetics RCV002366320 SCV002623843 uncertain significance Hereditary cancer-predisposing syndrome 2022-06-10 criteria provided, single submitter clinical testing The p.S1295G variant (also known as c.3883A>G), located in coding exon 20 of the BLM gene, results from an A to G substitution at nucleotide position 3883. The serine at codon 1295 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003102467 SCV003250558 uncertain significance Bloom syndrome 2021-12-15 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with BLM-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 1295 of the BLM protein (p.Ser1295Gly).
