Atypical split hand (left) was observed in one of monozygotic twins. The probability for monozygosity was 0.997 as based on 18 autosomal loci (11 blood groups and 7 enzymes and serum proteins). This observation supports the thesis that atypical split hand is not genetically determined and must be distinguished from autosomal dominant ectrodactyly.
在一对同卵双胞胎中观察到一例非典型裂手（左手）。基于18个常染色体位点（11个血型以及7种酶和血清蛋白），同卵性概率为0.997。该观察结果支持以下论点，即非典型裂手并非由基因决定，必须与常染色体显性缺指症相区分。
