Description

The p.D50H variant (also known as c.148G>C), located in coding exon 2 of the SDHB gene, results from a G to C substitution at nucleotide position 148. The aspartic acid at codon 50 is replaced by histidine, 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 alteration remains unclear.
