Genes affected

ERP44 (HGNC:18311): (endoplasmic reticulum protein 44) This gene encodes a member of the protein disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins. It has an inferred N-terminal signal peptide, a catalytically active thioredoxin (TRX) domain, two TRX-like domains and a C-terminal ER-retention sequence. This protein functions as a pH-regulated chaperone of the secretory pathway and likely plays a role in protein quality control at the endoplasmic reticulum - Golgi interface.

The c.426C>A (p.D142E) alteration is located in exon 5 (coding exon 5) of the ERP44 gene. This alteration results from a C to A substitution at nucleotide position 426, causing the aspartic acid (D) at amino acid position 142 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
