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.332A>G (p.K111R) alteration is located in exon 5 (coding exon 5) of the ERP44 gene. This alteration results from a A to G substitution at nucleotide position 332, causing the lysine (K) at amino acid position 111 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
