Genes affected

CEL (HGNC:1848): (carboxyl ester lipase) The protein encoded by this gene is a glycoprotein secreted from the pancreas into the digestive tract and from the lactating mammary gland into human milk. The physiological role of this protein is in cholesterol and lipid-soluble vitamin ester hydrolysis and absorption. This encoded protein promotes large chylomicron production in the intestine. Also its presence in plasma suggests its interactions with cholesterol and oxidized lipoproteins to modulate the progression of atherosclerosis. In pancreatic tumoral cells, this encoded protein is thought to be sequestrated within the Golgi compartment and is probably not secreted. This gene contains a variable number of tandem repeat (VNTR) polymorphism in the coding region that may influence the function of the encoded protein. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.014160126).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00174 (84/48336) while in subpopulation SAS AF = 0.00493 (8/1622). AF 95% confidence interval is 0.00245. There are 0 homozygotes in GnomAd4. There are 36 alleles in the male GnomAd4 subpopulation. Median coverage is 6. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 84 AD,Unknown gene.
