Invitae RCV000550356 SCV000623307 uncertain significance Bloom syndrome 2023-09-08 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1096 of the BLM protein (p.Gly1096Arg). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 454134). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BLM protein function. 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.
Ambry Genetics RCV002448597 SCV002612539 uncertain significance Hereditary cancer-predisposing syndrome 2022-03-12 criteria provided, single submitter clinical testing The p.G1096R variant (also known as c.3286G>A), located in coding exon 16 of the BLM gene, results from a G to A substitution at nucleotide position 3286. The glycine at codon 1096 is replaced by arginine, an amino acid with dissimilar 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.
