Genes affected

APOC3 (HGNC:610): (apolipoprotein C3) This gene encodes a protein component of triglyceride (TG)-rich lipoproteins (TRLs) including very low density lipoproteins (VLDL), high density lipoproteins (HDL) and chylomicrons. The encoded protein plays a role in role in the metabolism of these TRLs through multiple modes. This protein has been shown to promote the secretion of VLDL1, inhibit lipoprotein lipase enzyme activity, and delay catabolism of TRL remnants. Mutations in this gene are associated with low plasma triglyceride levels and reduced risk of ischemic cardiovascular disease, and hyperalphalipoproteinemia, which is characterized by elevated levels of high density lipoprotein (HDL) and HDL cholesterol in human patients. This gene and other related genes comprise an apolipoprotein gene cluster on chromosome 11. [provided by RefSeq, Sep 2017]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: -0.057647 (below the threshold of 3.09). Trascript score misZ: 0.23808 (below the threshold of 3.09). GenCC associations: The gene is linked to cholesterol-ester transfer protein deficiency.

BP4

Computational evidence support a benign effect (MetaRNN=0.018726647).

BP6

Variant 11-116830844-G-A is Benign according to our data. Variant chr11-116830844-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 139561.

BS2

High AC in GnomAd4 at 157 AD gene.
