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)

C12orf60 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.
