Genes affected
CCKAR (HGNC:1570): (cholecystokinin A receptor) This gene encodes a G-protein coupled receptor that binds non-sulfated members of the cholecystokinin (CCK) family of peptide hormones. This receptor is a major physiologic mediator of pancreatic enzyme secretion and smooth muscle contraction of the gallbladder and stomach. In the central and peripheral nervous system this receptor regulates satiety and the release of beta-endorphin and dopamine. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 25, 2024The c.1163G>T (p.C388F) alteration is located in exon 5 (coding exon 5) of the CCKAR gene. This alteration results from a G to T substitution at nucleotide position 1163, causing the cysteine (C) at amino acid position 388 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
