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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.134A>G (p.N45S) alteration is located in exon 3 (coding exon 3) of the ERP44 gene. This alteration results from a A to G substitution at nucleotide position 134, causing the asparagine (N) at amino acid position 45 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
