Ambry Genetics RCV004952548 SCV005547708 uncertain significance Hereditary cancer-predisposing syndrome 2024-11-18 criteria provided, single submitter clinical testing The c.2257G>T variant (also known as p.D753Y), located in coding exon 14 of the BRIP1 gene, results from a G to T substitution at nucleotide position 2257. The amino acid change results in aspartic acid to tyrosine at codon 753, an amino acid with highly dissimilar properties. However, this change occurs in the last base pair of coding exon 14, which makes it likely to have some effect on normal mRNA splicing. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and may result in the creation or strengthening of a novel splice donor site; however, direct evidence is insufficient at this time (Ambry internal data). In addition, this alteration is predicted to be deleterious by in silico analysis. This amino acid position is highly conserved in available vertebrate species. Based on the available evidence, the clinical significance of this variant remains unclear.
