Invitae RCV001064987 SCV001229925 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2023-07-18 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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 858986). 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). This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 1137 of the BRIP1 protein (p.Tyr1137His).
Department of Pathology and Laboratory Medicine, Sinai Health System RCV001357702 SCV001553250 uncertain significance Malignant tumor of breast no assertion criteria provided clinical testing The BRIP1 p.Tyr1137His variant was not identified in the literature nor was it identified in the dbSNP, or ClinVar. The variant was not identified in the following control databases: the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The p.Tyr1137 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
