Fetal hydantoin syndrome, also called fetal dilantin syndrome is a group of defects caused to the developing fetus by exposure to the teratogenic effects of phenytoin or carbamazepine. Dilantin is the brand name of the drug phenytoin sodium in the United States, commonly used in the treatment of epilepsy. It may also be called congenital hydantoin syndrome, Fetal Hydantoin Syndrome, Dilantin Embryopathy, or Phenytoin Embryopathy. Association with EPHX1 has been suggested. ==Signs and symptoms== About one third of children whose mothers are taking this drug during pregnancy typically have intrauterine growth restriction with a small head and develop minor dysmorphic craniofacial features and limb defects including hypoplastic nails and distal phalanges (birth defects). A smaller population will have growth problems and developmental delay, or intellectual disability. Methemoglobinemia is a rarely seen side effect. Heart defects and cleft lip may also be featured. 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「fetal hydantoin syndrome」の詳細全文を読む スポンサード リンク
