Genes affected

GUCY2C (HGNC:4688): (guanylate cyclase 2C) This gene encodes a transmembrane protein that functions as a receptor for endogenous peptides guanylin and uroguanylin, and the heat-stable E. coli enterotoxin. The encoded protein activates the cystic fibrosis transmembrane conductance regulator. Mutations in this gene are associated with familial diarrhea (autosomal dominant) and meconium ileus (autosomal recessive). [provided by RefSeq, Nov 2016]

GUCY2C-AS1 (HGNC:56054): (GUCY2C antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 12-14669704-T-G is Benign according to our data. Variant chr12-14669704-T-G is described in ClinVar as Likely_benign. ClinVar VariationId is 2869334.Status of the report is criteria_provided_single_submitter, 1 stars.
