Description

The p.G16C variant (also known as c.46G>T), located in coding exon 1 of the SDHD gene, results from a G to T substitution at nucleotide position 46. The glycine at codon 16 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is not well 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.
