Description

The p.M247V variant (also known as c.739A>G), located in coding exon 7 of the SDHB gene, results from an A to G substitution at nucleotide position 739. The methionine at codon 247 is replaced by valine, an amino acid with highly similar properties. In one study, this alteration was identified in a female patient diagnosed with high-grade vaginal fusocellular sarcoma and endometrial adenocarcinoma (de Angelis de Carvalho N et al. Cancers (Basel), 2020 Jul;12:). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
