Description

The p.M142V variant (also known as c.424A>G), located in coding exon 4 of the SDHA gene, results from an A to G substitution at nucleotide position 424. The methionine at codon 142 is replaced by valine, an amino acid with highly similar properties. 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.
