Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LRP5 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: Acts as a coreceptor with members of the frizzled family of seven-transmembrane spanning receptors to transduce signal by Wnt proteins (PubMed:11336703, PubMed:11448771, PubMed:15778503, PubMed:11719191, PubMed:15908424, PubMed:16252235). Activates the canonical Wnt signaling pathway that controls cell fate determination and self-renewal during embryonic development and adult tissue regeneration (PubMed:11336703, PubMed:11719191). In particular, may play an important role in the development of the posterior patterning of the epiblast during gastrulation (By similarity). During bone development, regulates osteoblast proliferation and differentiation thus determining bone mass (PubMed:11719191). Mechanistically, the formation of the signaling complex between Wnt ligand, frizzled receptor and LRP5 coreceptor promotes the recruitment of AXIN1 to LRP5, stabilizing beta- catenin/CTNNB1 and activating TCF/LEF-mediated transcriptional programs (PubMed:11336703, PubMed:25920554, PubMed:24706814, PubMed:14731402). Acts as a coreceptor for non-Wnt proteins, such as norrin/NDP. Binding of norrin/NDP to frizzled 4/FZD4-LRP5 receptor complex triggers beta-catenin/CTNNB1-dependent signaling known to be required for retinal vascular development (PubMed:27228167, PubMed:16252235). Plays a role in controlling postnatal vascular regression in retina via macrophage-induced endothelial cell apoptosis (By similarity). {ECO:0000250|UniProtKB:Q91VN0, ECO:0000269|PubMed:11336703, ECO:0000269|PubMed:11448771, ECO:0000269|PubMed:11719191, ECO:0000269|PubMed:14731402, ECO:0000269|PubMed:15778503, ECO:0000269|PubMed:15908424, ECO:0000269|PubMed:16252235, ECO:0000269|PubMed:24706814, ECO:0000269|PubMed:25920554, ECO:0000269|PubMed:27228167}.
• Disease: DISEASE: Vitreoretinopathy, exudative 1 (EVR1) [MIM:133780]: A disorder of the retinal vasculature characterized by an abrupt cessation of growth of peripheral capillaries, leading to an avascular peripheral retina. This may lead to compensatory retinal neovascularization, which is thought to be induced by hypoxia from the initial avascular insult. New vessels are prone to leakage and rupture causing exudates and bleeding, followed by scarring, retinal detachment and blindness. Clinical features can be highly variable, even within the same family. Patients with mild forms of the disease are asymptomatic, and their only disease related abnormality is an arc of avascular retina in the extreme temporal periphery. In many ways the disease resembles retinopathy of prematurity but there is no evidence of prematurity or small birth weight in the patient history. {ECO:0000269|PubMed:27228167}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Vitreoretinopathy, exudative 4 (EVR4) [MIM:601813]: A disorder of the retinal vasculature characterized by an abrupt cessation of growth of peripheral capillaries, leading to an avascular peripheral retina.

Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Osteoporosis (OSTEOP) [MIM:166710]: A systemic skeletal disorder characterized by decreased bone mass and deterioration of bone microarchitecture without alteration in the composition of bone. The result is fragile bones and an increased risk of fractures, even after minimal trauma. Osteoporosis is a chronic condition of multifactorial etiology and is usually clinically silent until a fracture occurs. {ECO:0000269|PubMed:14727154, ECO:0000269|PubMed:15824851, ECO:0000269|PubMed:16234968}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Osteoporosis-pseudoglioma syndrome (OPPG) [MIM:259770]: A disease characterized by congenital or infancy-onset blindness and severe juvenile-onset osteoporosis and spontaneous fractures. Additional clinical manifestations may include microphthalmos, abnormalities of the iris, lens or vitreous, cataracts, short stature, microcephaly, ligamental laxity, mental retardation and hypotonia. {ECO:0000269|PubMed:11719191, ECO:0000269|PubMed:16252235, ECO:0000269|PubMed:16679074, ECO:0000269|PubMed:17437160, ECO:0000269|PubMed:18602879}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: High bone mass trait (HBM) [MIM:601884]: Rare phenotype characterized by exceptionally dense bones. HBM individuals show otherwise a completely normal skeletal structure and no other unusual clinical findings. {ECO:0000269|PubMed:11741193, ECO:0000269|PubMed:12015390, ECO:0000269|PubMed:15143163, ECO:0000269|PubMed:15824861, ECO:0000269|PubMed:17295608}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Endosteal hyperostosis, Worth type (WENHY) [MIM:144750]: An autosomal dominant sclerosing bone dysplasia clinically characterized by elongation of the mandible, increased gonial angle, flattened forehead, and the presence of a slowly enlarging osseous prominence of the hard palate (torus palatinus). Serum calcium, phosphorus and alkaline phosphatase levels are normal. Radiologically, it is characterized by early thickening of the endosteum of long bones, the skull and of the mandible. With advancing age, the trabeculae of the metaphysis become thickened. WENHY becomes clinically and radiologically evident by adolescence, does not cause deformity except in the skull and mandible, and is not associated with bone pain or fracture. Affected patients have normal height, proportion, intelligence and longevity. {ECO:0000269|PubMed:12579474}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Osteopetrosis, autosomal dominant 1 (OPTA1) [MIM:607634]: A rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. Osteopetrosis occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. OPTA1 is an autosomal dominant form characterized by generalized osteosclerosis most pronounced in the cranial vault. Patients are often asymptomatic, but some suffer from pain and hearing loss. It appears to be the only type of osteopetrosis not associated with an increased fracture rate. {ECO:0000269|PubMed:12579474}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Van Buchem disease 2 (VBCH2) [MIM:607636]: VBCH2 is an autosomal dominant sclerosing bone dysplasia characterized by cranial osteosclerosis, thickened calvaria and cortices of long bones, enlarged mandible and normal serum alkaline phosphatase levels. {ECO:0000269|PubMed:12579474}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Polycystic liver disease 4 with or without kidney cysts (PCLD4) [MIM:617875]: A form of polycystic liver disease, an autosomal dominant hepatobiliary disease characterized by overgrowth of biliary epithelium and supportive connective tissue, resulting in multiple liver cysts. PCLD4 patients may also develop kidney cysts that usually do not result in clinically significant renal disease. {ECO:0000269|PubMed:24706814, ECO:0000269|PubMed:28375157}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Note=LRP5 variations may act as a disease modifier in autosomal dominant polycystic kidney disease (ADPKD) in patients who have causative mutations in PKD1. May contribute to the disease phenotype heterogeneity and hepatic cystogenesis. {ECO:0000269|PubMed:25920554}.
