Genes affected

TMX2 (HGNC:30739): (thioredoxin related transmembrane protein 2) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, a catalytically active thioredoxin domain, one transmembrane domain and a C-terminal ER-retention sequence. This protein is enriched on the mitochondria-associated-membrane of the ER via palmitoylation of two of its cytosolically exposed cysteines. [provided by RefSeq, Jan 2017]

Feb 05, 2024

The c.65C>T (p.A22V) alteration is located in exon 1 (coding exon 1) of the TMX2 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the alanine (A) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
