We report a case of Down syndrome with unusual chromosome translocation. The proband is a 1 year old male with 47, XY, der (5) t(5;21) (q11:q21), + der (5) t(5;21). The mother's karyotype was 46 XX, der (5) t(5,21) (q11:q21). The chromosome imbalance resulted from 3:1 meiotic segregation.
我们报告一例患有不寻常染色体易位的唐氏综合征病例。先证者是一名1岁男性，核型为47, XY, der (5) t(5;21) (q11:q21), + der (5) t(5;21)。母亲的核型为46 XX, der (5) t(5,21) (q11:q21)。染色体不平衡是由3:1减数分裂分离导致的。
