地方性克汀病(简称地克病)在我国智力低下患者中占有相当大的比重,广泛存在于广大山区,病区患病率在0.14～11.4％。其病因至今尚未完全阐明,一般公认的病因主要是环境缺碘。近年来,流行病学调查发现地克病有明显的家庭聚集性,难以用单一的的环境缺碘因素解释,提出该病与遗传因素有关,认为地克病是缺碘一遗传的多基因疾病。我们为了进一步探讨地克病的
Local cretinism (Dick’s disease) accounts for a significant proportion of patients with mental retardation in our country and is widespread in vast mountainous areas. The prevalence of endemic areas is between 0.14 and 11.4%. The etiology has not yet been fully elucidated, generally recognized as the main cause of iodine deficiency in the environment. In recent years, epidemiological survey found that grams of grams of disease significantly family aggregation, it is difficult to explain with a single factor of iodine deficiency in the environment, put forward the disease and genetic factors that Dick’s disease is a genetic deficiency of polygenes . We are going to discuss Dick’s disease further
