Genes affected
LDLR (HGNC:6547): (low density lipoprotein receptor) The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2022]

ACMG classification
Classification made for transcript
Verdict is Benign. Variant got -12 ACMG points.
BP4
?
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BS1
?
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0105 (1598/151722) while in subpopulation NFE AF= 0.0172 (1166/67930). AF 95% confidence interval is 0.0163. There are 15 homozygotes in gnomad4. There are 782 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
