Oculodentodigital syndrome (ODD syndrome) is an extremely rare genetic condition that typically results in small eyes, underdeveloped teeth, and syndactyly and malformation of the fourth and fifth fingers. It has also been called oculo-dento-digital syndrome, oculodentodigital dysplasia (ODDD), and oculodentoosseous dysplasia (ODOD). It is considered a kind of ectodermal dysplasia. ==Signs and symptoms== People with ODD syndrome often have a characteristic appearance. Visible features of the condition include: * small teeth that are prone to caries because of underdeveloped tooth enamel; * a long, thin nose; * unusually small eyes; and * type III syndactyly of the fourth and fifth fingers. Iris atrophy and glaucoma are more common than average.〔 The size of the eyes often interferes with learning to read; special eyeglasses may be required. Hair may be fine, thin, dry, or fragile; in some families, it is curly. Neurologic abnormalities may be seen in adults. The neurologic changes may appear earlier in each subsequent generation and can include abnormal white matter, conductive deafness, and various kinds of paresis, including ataxia, spastic paraplegia, difficulty controlling the eyes, and bladder and bowel disturbances. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oculodentodigital dysplasia」の詳細全文を読む スポンサード リンク
