Genes affected

AGR2 (HGNC:328): (anterior gradient 2, protein disulphide isomerase family member) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, a catalytically active thioredoxin domain, and a C-terminal ER-retention sequence. This protein plays a role in cell migration, cellular transformation and metastasis and is as a p53 inhibitor. As an ER-localized molecular chaperone, it plays a role in the folding, trafficking, and assembly of cysteine-rich transmembrane receptors and the cysteine-rich intestinal gylcoprotein mucin. This gene has been implicated in inflammatory bowel disease and cancer progression. [provided by RefSeq, Mar 2017]

Ambry Genetics

Dec 22, 2023

The c.358C>A (p.P120T) alteration is located in exon 6 (coding exon 5) of the AGR2 gene. This alteration results from a C to A substitution at nucleotide position 358, causing the proline (P) at amino acid position 120 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
