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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.

PP5

Variant 16-56982238-G-A is Pathogenic according to our data. Variant chr16-56982238-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 17524.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000105 (154/1461770) while in subpopulation EAS AF = 0.00292 (116/39700). AF 95% confidence interval is 0.00249. There are 1 homozygotes in GnomAdExome4. There are 73 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. 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 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
