Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM3 PM2

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1845+15C>A variant is classified as Uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying evidence codes (PM2 and PM3) as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1101/2021.03.17.21252755).The supporting evidence is as follows:PM2 - This variant is absent from gnomAD (gnomAD v2.1.1).PM3 - Variant meets PM2 and is identified in an index case published in PMID:30269829 with homozygous FH phenotype (LDL-C = 14.5 mmol/l) and also duplication of whole PCSK9 gene, classified as Pathogenic by the general ACMG guidelines.

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]

Collection Method: curation

The NM_000527.5(LDLR):c.1845+15C>A variant is classified as Uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying evidence codes (PM2 and PM3) as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1101/2021.03.17.21252755). The supporting evidence is as follows: PM2 - This variant is absent from gnomAD (gnomAD v2.1.1). PM3 - Variant meets PM2 and is identified in an index case published in PMID: 30269829 with homozygous FH phenotype (LDL-C = 14.5 mmol/l) and also duplication of whole PCSK9 gene, classified as Pathogenic by the general ACMG guidelines. -
