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 -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.058515072).

BP6

Variant 19-11131312-C-T is Benign according to our data. Variant chr19-11131312-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 374957.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=2, Benign=1, Likely_benign=2}.

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000171 (250/1461826) while in subpopulation EAS AF= 0.00486 (193/39698). AF 95% confidence interval is 0.0043. There are 2 homozygotes in gnomad4_exome. There are 106 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.

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.
