Congenital hypoplasia of the thumb is not a rare condition in clinical practice, but a familial occurrence of this condition is exceedingly rare. We report a family with familial congenital hypoplasia of the thumb. In three generations, five members were proved to be affected and another two were presumed to be affected. To our surprise, a younger sister of the propositus had tetralogy of Fallot and triphalangeal thumbs on both hands.
先天性拇指发育不全在临床实践中并非罕见病症，但这种病症的家族性发生极为罕见。我们报告了一个患有家族性先天性拇指发育不全的家族。在三代人中，有五名成员被证实患病，另有两名被推测患病。令我们惊讶的是，先证者的一个妹妹患有法洛四联症且双手均为三节拇指。
