Genes affected

PDIA3 (HGNC:4606): (protein disulfide isomerase family A member 3) This gene encodes a protein of the endoplasmic reticulum that interacts with lectin chaperones calreticulin and calnexin to modulate folding of newly synthesized glycoproteins. The protein was once thought to be a phospholipase; however, it has been demonstrated that the protein actually has protein disulfide isomerase activity. It is thought that complexes of lectins and this protein mediate protein folding by promoting formation of disulfide bonds in their glycoprotein substrates. This protein also functions as a molecular chaperone that prevents the formation of protein aggregates. [provided by RefSeq, Dec 2016]

PDIA3 links:

CATSPER2P1 (HGNC:31054): (CATSPER2 pseudogene 1) Catsper genes belong to a family of putative cation channels that are specific to spermatozoa and localize to the flagellum. This gene is part of a tandem repeat on chromosome 15q15; this copy of the gene is thought to be a pseudogene. [provided by RefSeq, Oct 2008]

Ambry Genetics

May 17, 2023

The c.5G>A (p.R2H) alteration is located in exon 1 (coding exon 1) of the PDIA3 gene. This alteration results from a G to A substitution at nucleotide position 5, causing the arginine (R) at amino acid position 2 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
