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]

Collection Method: clinical testing

The c.16C>A (p.P6T) alteration is located in exon 1 (coding exon 1) of the ERP29 gene. This alteration results from a C to A substitution at nucleotide position 16, causing the proline (P) at amino acid position 6 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
