Ambry Genetics RCV003385866 SCV004091320 uncertain significance Hereditary cancer-predisposing syndrome 2023-07-26 criteria provided, single submitter clinical testing The p.D152H variant (also known as c.454G>C), located in coding exon 4 of the BRIP1 gene, results from a G to C substitution at nucleotide position 454. The aspartic acid at codon 152 is replaced by histidine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious 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 RCV003778095 SCV004588531 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2022-10-29 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 152 of the BRIP1 protein (p.Asp152His). 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on BRIP1 protein function. This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is not present in population databases (gnomAD no frequency).
