| Disease ID | Source | Name | Description |
| 607636 | OMIM | Van Buchem disease 2 (VBCH2) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 259770 | OMIM | Osteoporosis-pseudoglioma syndrome (OPPG) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 617875 | OMIM | Polycystic liver disease 4 with or without kidney cysts (PCLD4) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 607634 | OMIM | Osteopetrosis, autosomal dominant 1 (OPTA1) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 133780 | OMIM | Vitreoretinopathy, exudative 1 (EVR1) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 601813 | OMIM | Vitreoretinopathy, exudative 4 (EVR4) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 144750 | OMIM | Endosteal hyperostosis, Worth type (WENHY) | 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. The disease is caused by variants affecting the gene represented in this entry. |
| 601884 | OMIM | High bone mass trait (HBM) | Rare phenotype characterized by exceptionally dense bones. HBM individuals show otherwise a completely normal skeletal structure and no other unusual clinical findings. The disease is caused by variants affecting the gene represented in this entry. |
| 166710 | OMIM | Osteoporosis (OSTEOP) | 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. Disease susceptibility is associated with variants affecting the gene represented in this entry. |
