The occurrence of trisomy 13 in twins is very rare. We report a pair of genotypically identical twins with trisomy 13 discordant for major anomalies. This case contributes to the already published data on the contribution of non-genetic factors to the aetiology of congenital malformations in monozygotic twins.
13三体在双胞胎中极为罕见。我们报告了一对基因型相同但13三体且主要异常情况不一致的双胞胎。该病例为已发表的关于非遗传因素对单卵双胞胎先天性畸形病因学贡献的数据增添了内容。
