Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LDLR gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells by endocytosis. In order to be internalized, the receptor-ligand complexes must first cluster into clathrin-coated pits. {ECO:0000269|PubMed:3005267, ECO:0000269|PubMed:6091915}.; FUNCTION: (Microbial infection) Acts as a receptor for Vesicular stomatitis virus. {ECO:0000269|PubMed:23589850}.;
Disease
DISEASE: Familial hypercholesterolemia (FH) [MIM:143890]: A common autosomal dominant disorder characterized by elevated serum low- density lipoprotein (LDL) cholesterol levels, which result in excess deposition of cholesterol in tissues and leads to xanthelasma, xanthomas, accelerated atherosclerosis and increased risk of premature coronary heart disease. The disorder occurs in 2 clinical forms: a mild form that becomes evident in the fourth or fifth decade in individuals carrying heterozygous LDLR mutations; a more severe form that usually manifests in the first two decades of life in individuals with homozygous LDLR mutations. {ECO:0000269|PubMed:10090484, ECO:0000269|PubMed:10206683, ECO:0000269|PubMed:10422803, ECO:0000269|PubMed:10447263, ECO:0000269|PubMed:10532689, ECO:0000269|PubMed:10660340, ECO:0000269|PubMed:10882754, ECO:0000269|PubMed:10978268, ECO:0000269|PubMed:10980548, ECO:0000269|PubMed:11298688, ECO:0000269|PubMed:11462246, ECO:0000269|PubMed:1446662, ECO:0000269|PubMed:1464748, ECO:0000269|PubMed:17142622, ECO:0000269|PubMed:17347910, ECO:0000269|PubMed:1867200, ECO:0000269|PubMed:19318025, ECO:0000269|PubMed:19319977, ECO:0000269|PubMed:22160468, ECO:0000269|PubMed:22509010, ECO:0000269|PubMed:2318961, ECO:0000269|PubMed:24529145, ECO:0000269|PubMed:25378237, ECO:0000269|PubMed:25545329, ECO:0000269|PubMed:2569482, ECO:0000269|PubMed:2726768, ECO:0000269|PubMed:3263645, ECO:0000269|PubMed:3955657, ECO:0000269|PubMed:7550239, ECO:0000269|PubMed:7573037, ECO:0000269|PubMed:7583548, ECO:0000269|PubMed:7635461, ECO:0000269|PubMed:7635482, ECO:0000269|PubMed:7649546, ECO:0000269|PubMed:7649549, ECO:0000269|PubMed:8168830, ECO:0000269|PubMed:8347689, ECO:0000269|PubMed:8462973, ECO:0000269|PubMed:8664907, ECO:0000269|PubMed:8740918, ECO:0000269|PubMed:9026534, ECO:0000269|PubMed:9104431, ECO:0000269|PubMed:9143924, ECO:0000269|PubMed:9254862, ECO:0000269|PubMed:9259195, ECO:0000269|PubMed:9452094, ECO:0000269|PubMed:9452095, ECO:0000269|PubMed:9452118, ECO:0000269|PubMed:9654205, ECO:0000269|PubMed:9678702, ECO:0000269|PubMed:9852677, ECO:0000269|Ref.71}.
