Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

This summary comes from the ClinGen Evidence Repository: NM_000527.4(LDLR): c.2448G>C (p.Lys816Asn) variant is classified as Uncertain significance - insufficient evidence, for Familial Hypercholesterolemia by applying evidence codes PM2, as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1016/j.gim.2021.09.012). The supporting evidence is as follows: . PM2: PopMax MAF = 0.00006482 (0.007%) in European (Non-Finnish) exomes+genomes (gnomAD v2.1.1).. BP4: REVEL = 0.5. It is not below 0.5, splicing evaluation is needed. Functional data on splicing not available. A) variant is not on limitsB) Variant does not create GT or AGVariant is not predicted to affect splicing. LINK:https://erepo.genome.network/evrepo/ui/classification/CA404098878/MONDO:0007750/013

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]
