Description

The p.L61V variant (also known as c.181C>G), located in coding exon 2 of the BRCA2 gene, results from a C to G substitution at nucleotide position 181. The leucine at codon 61 is replaced by valine, an amino acid with highly similar properties. This amino acid position is poorly 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.
