Osteogenesis imperfecta

COL1A1/2-related osteogenesis imperfecta (OI) is characterized by fractures with minimal or absent trauma, variable dentinogenesis imperfecta (DI), and, in adult years, hearing loss. The clinical features of COL1A1/2-related OI represent a continuum ranging from perinatal lethality to individuals with severe skeletal deformities, mobility impairments, and very short stature to nearly asymptomatic individuals with a mild predisposition to fractures, normal dentition, normal stature, and normal life span. Fractures can occur in any bone, but are most common in the extremities. DI is characterized by grey or brown teeth that may appear translucent and wear down and break easily. COL1A1/2-related OI has been classified into four types (I, II, III, and IV) based on clinical presentation and radiographic findings. This classification system can be helpful in providing information about prognosis and management for a given individual. The four OI types are now referred to as follows: OI type I: classic non-deforming OI with blue sclerae. OI type II: perinatally lethal OI. OI type III: progressively deforming OI. OI type IV: common variable OI with normal sclerae. [from GeneReviews]

Osteoporosis

Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis. Risk factors include . - Getting older . - Being small and thin . - Having a family history of osteoporosis. - Taking certain medicines. - Being a white or Asian woman. - Having osteopenia, which is low bone density. Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health. To keep bones strong, eat a diet rich in calcium and vitamin D, exercise and do not smoke. If needed, medicines can also help. .

Osteoporosis

Metabolic disorder associated with fractures of the femoral neck, vertebrae, and distal forearm. It occurs commonly in women within 15-20 years after menopause, and is caused by factors associated with menopause including estrogen deficiency. [from MeSH]

Inborn genetic diseases

Diseases that are caused by genetic mutations present during embryo or fetal development, although they may be observed later in life. The mutations may be inherited from a parent's genome or they may be acquired in utero. [from MeSH]

Osteopenia

Osteopenia refers to a reduction in bone mineral density (BMD) below normal peak BMD but not low enough to be classified as osteoporosis. According to the WHO, osteopenia is characterized by a value of BMD more than 1 standard deviation below the young adult mean, but less than 2 standard deviations below this value. [from HPO]

Osteogenesis imperfecta type 12

Osteogenesis imperfecta (OI) comprises a group of connective tissue disorders characterized by bone fragility and low bone mass. The disorder is clinically and genetically heterogeneous. Osteogenesis imperfecta type VI is a severe autosomal recessive form of the disorder (Glorieux et al., 2002; Becker et al., 2011). [from OMIM]

Osteogenesis imperfecta type 11

Osteogenesis imperfecta (OI) comprises a group of connective tissue disorders characterized by bone fragility and low bone mass. The disorder is clinically and genetically heterogeneous. OI type XII is an autosomal recessive form characterized by recurrent fractures, mild bone deformations, generalized osteoporosis, delayed teeth eruption, no dentinogenesis imperfecta, normal hearing, and white sclerae (summary by Lapunzina et al., 2010). [from OMIM]

Multiple Epiphyseal Dysplasia, Dominant

Autosomal dominant multiple epiphyseal dysplasia (MED) presents in early childhood, usually with pain in the hips and/or knees after exercise. Affected children complain of fatigue with long-distance walking. Waddling gait may be present. Adult height is either in the lower range of normal or mildly shortened. The limbs are relatively short in comparison to the trunk. Pain and joint deformity progress, resulting in early-onset osteoarthritis, particularly of the large weight-bearing joints. [from GeneReviews]

Osteogenesis imperfecta type 8

Osteogenesis imperfecta (OI) is a connective tissue disorder characterized by bone fragility and low bone mass. Due to considerable phenotypic variability, Sillence et al. (1979) developed a classification of OI subtypes based on clinical features and disease severity: OI type I, with blue sclerae (166200); perinatal lethal OI type II, also known as congenital OI (166210); OI type III, a progressively deforming form with normal sclerae (259420); and OI type IV, with normal sclerae (166220). Most forms of OI are autosomal dominant with mutations in one of the 2 genes that code for type I collagen alpha chains, COL1A1 (120150) and COL1A2 (120160). Cabral et al. (2007) described a form of autosomal recessive OI, which they designated OI type VIII, characterized by white sclerae, severe growth deficiency, extreme skeletal undermineralization, and bulbous metaphyses. [from OMIM]

Multiple epiphyseal dysplasia 4

Recessive multiple epiphyseal dysplasia (EDM4/rMED) is characterized by joint pain (usually in the hips or knees); malformations of hands, feet, and knees; and scoliosis. Approximately 50% of affected individuals have an abnormal finding at birth, e.g., clubfoot, clinodactyly, or (rarely) cystic ear swelling. Onset of articular pain is variable but usually occurs in late childhood. Stature is usually within the normal range prior to puberty; in adulthood, stature is only slightly diminished and ranges from 150 to 180 cm. Functional disability is mild. [from GeneReviews]
