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]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.017394722).
• BP6: Variant 4-26481832-C-T is Benign according to our data. Variant chr4-26481832-C-T is described in ClinVar as Benign. ClinVar VariationId is 17530.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00698 (1063/152292) while in subpopulation AFR AF = 0.0236 (979/41560). AF 95% confidence interval is 0.0223. There are 12 homozygotes in GnomAd4. There are 482 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 12 AR gene
