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]

Jan 31, 2023

The c.344A>G (p.K115R) alteration is located in exon 3 (coding exon 2) of the TXN2 gene. This alteration results from a A to G substitution at nucleotide position 344, causing the lysine (K) at amino acid position 115 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
