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 -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.66).

BP6

Variant 19-11120223-C-A is Benign according to our data. Variant chr19-11120223-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 252142.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-11120223-C-A is described in Lovd as [Benign]. Variant chr19-11120223-C-A is described in Lovd as [Likely_benign].

BP7

Synonymous conserved (PhyloP=-1.26 with no splicing effect.

BS2

High Homozygotes in GnomAdExome4 at 2 SD geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
