Genes affected

CETP (HGNC:1869): (cholesteryl ester transfer protein) The protein encoded by this gene is found in plasma, where it is involved in the transfer of cholesteryl ester from high density lipoprotein (HDL) to other lipoproteins. Defects in this gene are a cause of hyperalphalipoproteinemia 1 (HALP1). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 16-56978467-T-G is Benign according to our data. Variant chr16-56978467-T-G is described in ClinVar as [Benign]. Clinvar id is 1278306.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr16-56978467-T-G is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.373 is higher than 0.05.
