摘　　要：报告1例结婚3年未避孕未孕的女性患者及其亲属的细胞遗传学分析。采用外周血细胞遗传学分析技术检测患者及其亲属的染色体核型。患者染色体核型为45,XX,inv(2)(p23q21),der(14;22)(q10;q10),患者父亲核型为45,XY,der(14;22)(q10;q10),患者二姐核型为45,XX,der(14;22)(q10;q10),其母亲、丈夫及大姐核型正常。患者既存在2号染色体的臂间倒位,又存在14号染色体和22号染色体的罗伯逊易位,两种染色体易位均可能是造成其不孕的原因。We report the cytogenetic analysis of a female patient who had been married for three years without pregnancy and her relatives.The karyotypes of the patient and the relatives were detected by peripheral blood cytogenetic analysis.The karyotypes of the patients were 45,XX,inv(2)(p23q21),der(14;22)(q10;q10),the father karyotype of the patient was 45,XY,der(14;22)(q10;q10),the karyotype of second sister was 45,XX,der(14;22)(q10;q10).Her mother,husband and eldest sister had normal karyotypes.The patient had both interbrachial inversion on chromosome 2 and Robertson translocation on chromosome 14 and chromosome 22,both of them may be the cause of infertility.
