Genes affected
ERP29 (HGNC:13799): (endoplasmic reticulum protein 29) This gene encodes a protein which localizes to the lumen of the endoplasmic reticulum (ER). It is a member of the protein disulfide isomerase (PDI) protein family but lacks an active thioredoxin motif, suggesting that this protein does not function as a disulfide isomerase. The canonical protein dimerizes and is thought to play a role in the processing of secretory proteins within the ER. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2016]

The c.250G>A (p.D84N) alteration is located in exon 2 (coding exon 2) of the ERP29 gene. This alteration results from a G to A substitution at nucleotide position 250, causing the aspartic acid (D) at amino acid position 84 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
