Description

The p.S299C variant (also known as c.895A>T), located in coding exon 11 of the TXNRD2 gene, results from an A to T substitution at nucleotide position 895. The serine at codon 299 is replaced by cysteine, an amino acid with dissimilar properties. This amino acid position is poorly conserved in available vertebrate species, and cysteine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
