Description

The p.R79Q variant (also known as c.236G>A), located in coding exon 4 of the TXNRD2 gene, results from a G to A substitution at nucleotide position 236. The arginine at codon 79 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is not well conserved in available 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.
