Description

The p.T203A variant (also known as c.607A>G), located in coding exon 5 of the SDHA gene, results from an A to G substitution at nucleotide position 607. The threonine at codon 203 is replaced by alanine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
