He died suddenly and inexplicably at 4 years of age. If you have one copy of the gene, you will have the disease. Signs and Symptoms of Type I OI OI affects people in several ways and this may vary from person to person. While the skeletal manifestations are more predominant, OI can also present with ocular complications such as blue sclera, hyperopic or myopic eyes, retinal detachments, decreased corneal rigidity, and glaucoma. Osteogenesis imperfecta (OI) causes bones to be fragile and easily broken and is also responsible for other health problems. Because the symptoms of OI are caused by collagen abnormalities and not a calcium deficiency . * Sclera (whites of the eyes) usually have a blue, purple, or gray tint. The body uses type 1 collagen to make bones strong and to build tendons, ligaments, teeth, and the whites of the eyes. Treatment is based on a child's specific symptoms, and can include physical therapy and mobility aides, occupational therapy . Mild or no bone deformity. (OI) is a group of genetic disorders that mainly affect the bones. Causes Osteogenesis imperfecta (OI) is present at birth. There are 8 main types of osteogenesis imperfecta. Symptoms vary, but may include easily broken bones, mild short stature, dentinogenesis imperfecta, adult-onset hearing loss, and normal-to-grey sclerae (the whites of the eye). A rare genetic connective tissue disorder characterized by fragile bones and hyperextensible joints - a type of osteogenesis imperfecta I where the teeth are opalescent and blue sclerae may be absent. It's also known as brittle bone disease. Weak, brittle or discolored teeth. In this type, the structure of the collagen protein is normal but there is less production of the protein than normal. Triangular-shaped face. Bruising easily. Of the 16 types of OI, type 1 is the mildest form and type 2 is the most severe. He also had blue sclerae and abnormal teeth. Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones.Osteogenesis imperfecta type 1 is the mildest form of OI and is characterized by bone fractures during childhood and adolescence that often result from minor trauma. Unlike more severely affected individuals, people with type I are usually of normal or near normal height. There are many defects that can affect this gene. Other associated signs and symptoms include blue/gray tint to the whites of the eyes, hearing loss, dental issues, looseness of skin or joints, and easy bruising as collagen contributes to the structure of the skin and other parts of the body. The following is a list of signs and symptoms common among people with Type I OI. People who have type I OI have bone fractures during childhood and adolescence often due to minor trauma When these individuals reach adulthood they have fewer fractures. Type I OI is the mildest form of the condition. hearing loss (type 1 and 3) heart failure (type 2) respiratory problems and pneumonias due to chest wall deformities. Nearly ninety percent are due to Type I collagen mutations. A person is born with OI, and is affected throughout his or her lifetime. The severity of OI depends on the specific gene defect. Brittle bone disease, or osteogenesis imperfecta, is a lifelong and potentially life-threatening disorder that makes bones break very easily. At birth, the symptoms of OI Type III . Joints can be hypermobile or very flexible Some degree of joint or bone pain may be present Problems with formation of teeth (dentinogenesis, or DI) Children with OI may tire easier than other children Hearing problems are known to affect people with OI usually after puberty. As with type 3 OI, your body produces enough collagen but the quality is poor. Certain gene changes, or mutations, cause the collagen defects. Osteogenesis Imperfecta, Type IV is a rare disease. [edoj.org.eg] Osteogenesis imperfecta (OI) is a genetic disorder that is characterized by recurrent fractures, low bone mass, blue sclera and dentinogenesis imperfecta (DI). Osteogenesis imperfecta type 1 is the mildest form of OI and is characterized by bone fractures during childhood and adolescence that often result from minor trauma . The estimated number varies greatly because milder forms of osteogenesis imperfecta can go undiagnosed. All cases of type 1 walked. Osteogenesis imperfecta type 1 is the mildest form of OI and is characterized by bone fractures during childhood and adolescence that often result from minor trauma. [5] In moderate and especially severe OI, the long bones may be bowed, sometimes extremely so. Go To Source: Orphanet. Last Reviewed 2019-07. This test can detect abnormal collage type I structure or synthesis in upto 90 percent of patients. If one parent has osteogenesis imperfecta, a child has a 50 percent chance of having the condition. Type I-IV are autosomal dominant, and Type VI-XIII are. Osteogenesis Imperfecta Overview. Bowed legs and arms. It is often caused by a defect in the gene that produces type 1 collagen, an important building block of bone. Other symptoms, such as easy bruising and bleeding complications during surgery necessitating transfusions, have also been reported. Two sibs, in a large dominant pedigree of OI reported by Rouviere et al., (2004) developed a dissection of the carotid artery. Osteogenesis Imperfecta is a common congenital disorder caused by a mutation in COL1A1 or COL1A2 genes resulting in abnormal collagen cross-linking and overall decrease in type 1 collagen. Scoliosis - a lateral, or sideways curvature and rotation of the back bones (vertebrae), giving the appearance that the person is leaning to one side. People with type 1 tend to have mild symptoms. Symptoms may range from mild to severe.. Type 1 collagen, which constitutes approximately 30% of the human body weight is defective in osteogenesis imperfecta. Skin biopsy is the definitive method of diagnosis for osteogenesis imperfecta types I through IV. Most of the mutations that cause osteogenesis imperfecta type 1 occur in the COL1A1 gene. Laboratory values. . Height that is short, below average. Osteogenesis imperfecta has no cure, but individuals can help prevent the disease or treat it with conventional and home remedies. The whites of the eyes may appear more blue or grey than normal. The whites of their eyes can have a blueish tint. Most prominent signs are fractures due to low traumata and deformities of long bones and vertebrae. There are at least 8 different types of . Clinical diagnosis could be verified by moleculargenetic analysis, a newly recognized heterozygous . Diagnosis and Tests superimposed on a background of OI. Type 4 OI is the most variable form of brittle bone disease because its symptoms range from mild to severe. In the United States, the incidence of osteogenesis imperfecta is estimated to be one per 20,000 live births. Curved spine with potential for compression of the vertebrae (spine bones) with aging. [malacards.org] sclerae which remain intensely blue throughout life, in contrast to the sclerae in OI type III and OI type IV which may also be blue at birth and during infancy. Loose joints. Symptoms of additional bone loss may appear at a younger age than commonly seen in people who do not have OI. He was originally diagnosed with Stuve-Wiedemann syndrome ( 601559 ), but his symptoms later became more consistent with a diagnosis of OI, with 4 spontaneous fractures and vertebral collapses in the first 2 years of life. To confirm a diagnosis, a doctor may recommend genetic testing. Blue, purple, or gray tint to sclera (whites of the eyes).
