Description

The p.D2811N variant (also known as c.8431G>A), located in coding exon 18 of the BRCA2 gene, results from a G to A substitution at nucleotide position 8431. The aspartic acid at codon 2811 is replaced by asparagine, an amino acid with highly similar properties. This variant was reported in one individual in a cohort of patients admitted to a Turkish medical genetics clinic for breast cancer (Subaolu A et al. Eur J Breast Health, 2023 Jan;19:55-69). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
