Genes affected

TMX4 (HGNC:25237): (thioredoxin related transmembrane protein 4) 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 C-terminal ASP/GLU-rich calcium binding domain. Unlike most members of this gene family, it lacks a C-terminal ER-retention sequence. The encoded protein has been shown to have reductase activity in vitro. [provided by RefSeq, Jan 2017]

The c.523A>T (p.N175Y) alteration is located in exon 6 (coding exon 6) of the TMX4 gene. This alteration results from a A to T substitution at nucleotide position 523, causing the asparagine (N) at amino acid position 175 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
