Genes affected

TXN2 (HGNC:17772): (thioredoxin 2) This nuclear gene encodes a mitochondrial member of the thioredoxin family, a group of small multifunctional redox-active proteins. The encoded protein may play important roles in the regulation of the mitochondrial membrane potential and in protection against oxidant-induced apoptosis. [provided by RefSeq, Jul 2008]

The c.496G>A (p.G166S) alteration is located in exon 4 (coding exon 3) of the TXN2 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the glycine (G) at amino acid position 166 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
