disease:Defects in ANO5 are the cause of gnathodiaphyseal dysplasia (GDD) [MIM:166260]; also called osteogenesis imperfecta with unusual skeletal lesions or gnathodiaphyseal sclerosis. GDD is a rare skeletal syndrome characterized by bone fragility, sclerosis of tubular bones, and cemento-osseous lesions of the jawbone. Patients experience frequent bone fractures caused by trivial accidents in childhood; however the fractures heal normally without bone deformity. The jaw lesions replace the tooth-bearing segments of the maxilla and mandible with fibrous connective tissues, including various amounts of cementum-like calcified mass, sometimes causing facial deformities. Patients also have a propensity for jaw infection and often suffer from purulent osteomyelitis-like symptoms, such as swelling of and pus discharge from the gums, mobility of the teeth, insufficient healing after tooth extraction and exposure of the lesions into the oral cavity.,function:May act as a calcium-activated chloride channel.,similarity:Belongs to the anoctamin family.,subcellular location:Co-localized with CALR/calreticulin.,tissue specificity:Highly expressed in brain, heart, kidney, lung, and skeletal muscle. Weakly expressed in bone marrow, fetal liver, placenta, spleen, thymus, osteoblasts and periodontal ligament cells.,
