Genes affected

PDIA5 (HGNC:24811): (protein disulfide isomerase family A member 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 ER-signal sequence, three catalytically active thioredoxin (TRX) domains, a TRX-like domain, and a C-terminal ER-retention sequence. The N-terminal TRX-like domain is the primary binding site for the major ER chaperone calreticulin and possibly other proteins and substrates as well. Alternative splicing results in multiple protein- and non-protein-coding transcript variants. [provided by RefSeq, Dec 2016]

The c.137G>A (p.R46Q) alteration is located in exon 2 (coding exon 2) of the PDIA5 gene. This alteration results from a G to A substitution at nucleotide position 137, causing the arginine (R) at amino acid position 46 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
