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 GeneticsApr 27, 2022The c.799G>A (p.D267N) alteration is located in exon 5 (coding exon 5) of the CCKAR gene. This alteration results from a G to A substitution at nucleotide position 799, causing the aspartic acid (D) at amino acid position 267 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
