Genes affected
APOE (HGNC:613): (apolipoprotein E) The protein encoded by this gene is a major apoprotein of the chylomicron. It binds to a specific liver and peripheral cell receptor, and is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. This gene maps to chromosome 19 in a cluster with the related apolipoprotein C1 and C2 genes. Mutations in this gene result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PP5
Variant 19-44907777-G-A is Pathogenic according to our data. Variant chr19-44907777-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 17849.Status of the report is no_assertion_criteria_provided, 0 stars.
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000678 (99/1459790) while in subpopulation EAS AF= 0.00247 (98/39678). AF 95% confidence interval is 0.00207. There are 0 homozygotes in gnomad4_exome. There are 41 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
