The c.5152T>G variant (also known as p.W1718G), located in coding exon 16 of the BRCA1 gene, results from a T to G substitution at nucleotide position 5152. The amino acid change results in tryptophan to glycine at codon 1718, an amino acid with highly dissimilar properties. However, this change occurs in the last base pair of coding exon 16, which makes it likely to have some effect on normal mRNA splicing. This amino acid position is highly conserved in available vertebrate species. 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.
