Ambry Genetics RCV002325068 SCV002606988 uncertain significance Hereditary cancer-predisposing syndrome 2016-11-04 criteria provided, single submitter clinical testing The p.C1094R variant (also known as c.3280T>C), located in coding exon 19 of the BRIP1 gene, results from a T to C substitution at nucleotide position 3280. The cysteine at codon 1094 is replaced by arginine, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 175000 alleles tested) in our clinical cohort. This amino acid position is not well conserved in available vertebrate species. 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.
Color Diagnostics, LLC DBA Color Health RCV002325068 SCV004362878 uncertain significance Hereditary cancer-predisposing syndrome 2022-08-01 criteria provided, single submitter clinical testing This missense variant replaces cysteine with arginine at codon 1094 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
