The UCLA Registry for Genetic Studies in Autism was established in 1980 to test the hypothesis that genetic factors may be etiologically significant in subsets of patients. To date 61 pairs of twins have enrolled and 40 meet research diagnostic criteria for autism. The authors found a concordance for autism in these 40 pairs of 95.7% in the monozygotic twins (22 of 23) and 23.5% in the dizygotic twins (four of 17).
加州大学洛杉矶分校自闭症遗传研究登记处成立于1980年,旨在验证遗传因素在部分患者病因中可能具有重要意义这一假设。到目前为止,已有61对双胞胎登记在册,其中40对符合自闭症的研究诊断标准。作者发现,在这40对双胞胎中,单卵双胞胎(23对中的22对)的自闭症一致率为95.7%,双卵双胞胎(17对中的4对)的一致率为23.5%。
