Description

The p.Q154R variant (also known as c.461A>G), located in coding exon 4 of the BRCA2 gene, results from an A to G substitution at nucleotide position 461. The glutamine at codon 154 is replaced by arginine, an amino acid with highly similar properties. This alteration was identified in 1/507 unselected Chinese breast cancer patients (Zhong X et al. PLoS One, 2016 Jun;11:e0156789). This amino acid position is highly 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.
