Genes affected

TXNDC5 (HGNC:21073): (thioredoxin domain containing 5) 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 endoplasmic reticulum (ER)-signal sequence, three catalytically active thioredoxin domains and a C-terminal ER-retention sequence. Its expression is induced by hypoxia and its role may be to protect hypoxic cells from apoptosis. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring upstream BLOC1S5 gene. [provided by RefSeq, Dec 2016]

TXNDC5 links:

BLOC1S5-TXNDC5 (HGNC:42001): (BLOC1S5-TXNDC5 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring MUTED (muted homolog) and TXNDC5 (thioredoxin domain containing 5) genes on chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

The c.1051G>A (p.G351S) alteration is located in exon 9 (coding exon 9) of the TXNDC5 gene. This alteration results from a G to A substitution at nucleotide position 1051, causing the glycine (G) at amino acid position 351 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
