Description

The p.D3260E variant (also known as c.9780T>G), located in coding exon 26 of the BRCA2 gene, results from a T to G substitution at nucleotide position 9780. The aspartic acid at codon 3260 is replaced by glutamic acid, an amino acid with highly similar properties. 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.
