In reciprocal translocations, nonhomologous Robertsonian translocations and homologous Robertsonian translocations, the birth defects rates were 5.7% ( 20/ 350), 10.9% ( 14/ 128) and 8.0% ( 2/ 25), respectively ( P < 0.05).

Results There were 38 chromosome aberrations ( 29 women, 9 men) in them, the abnormal rate being 3.2%, including 31 balanced translocations ( 16 reciprocal translocations, 15 Robertsonian translocations), 6 pericentric inversions, and 1 mosaic.

结果发现染色体异常核型38例，异常发生率为3.2%。其中平衡易位31例（相互易位16例，罗伯逊易位15例），臂间倒位6例，嵌合体1例；
