This case study describes a female monozygotic twinship in which one of the twins presented with anorexia nervosa. The case supports the suggestion from the few such discordant pairs previously reported that the affected twin tends to have been relatively disadvantaged from an early age and to be the less dominant of the pair. A review of previously reported cases suggests a concordance rate for anorexia nervosa of about 50% in female MZ twin pairs. Some methodological problems associated with the derivation of such estimates are noted.
本案例研究描述了一对女性同卵双胞胎，其中一个患有神经性厌食症。该案例支持了先前报道的少数此类不一致双胞胎对的观点，即受影响的双胞胎往往从小就相对处于不利地位，并且在双胞胎对中处于较不占主导地位的一方。对先前报道案例的回顾表明，女性同卵双胞胎对中神经性厌食症的一致率约为50%。同时也指出了与得出此类估计值相关的一些方法学问题。
