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]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a chain Anterior gradient protein 2 homolog (size 154) in uniprot entity AGR2_HUMAN there are 8 pathogenic changes around while only 1 benign (89%) in NM_006408.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.957
• PP5: Variant 7-16801196-G-T is Pathogenic according to our data. Variant chr7-16801196-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2443885.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr7-16801196-G-T is described in Lovd as [Pathogenic].
