Description

The p.E324K variant (also known as c.970G>A), located in coding exon 8 of the SDHA gene, results from a G to A substitution at nucleotide position 970. The glutamic acid at codon 324 is replaced by lysine, an amino acid with 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. Based on the available evidence, the clinical significance of this variant remains unclear.
