Description

The p.V115I variant (also known as c.343G>A), located in coding exon 4 of the SDHD gene, results from a G to A substitution at nucleotide position 343. The valine at codon 115 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is conserved. 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.
