The p.R612G variant (also known as c.1834A>G), located in coding exon 9 of the BRCA1 gene, results from an A to G substitution at nucleotide position 1834. The arginine at codon 612 is replaced by glycine, an amino acid with dissimilar properties. Using a comparative evolutionary approach, multiple studies have predicted that this missense alteration affects protein function because it occurs at a conservative site (Fleming MA et al. Proc Natl Acad Sci U S A. 2003 Feb 4;100(3):1151-6; Burk-Herrick A et al. Mamm Genome. 2006 Mar;17(3):257-70; Ramirez CJ et al. Oncogene. 2004 Mar 4;23(9):1780-8). 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.
