本文报道了一例极为罕见的、涉及六条染色体有三个易位的染色体结构畸变。患者为10个月龄的幼儿,智力明显低下。取外周血淋巴细胞作G显带染色体标本,核型分析60个中期细胞的结果,每个核型均具有涉及2、3;6、15;7、14号六条染色体的三个易位,其核型按国际体制可表示为46,XY,t(2;3)(q37;q25),t(6;15)(q13;p11),t(7;14)(q11;q13)。 This article reports an extremely rare chromosomal structural aberration involving three translocations of six chromosomes. The patient is a 10-month-old child with significantly lower intelligence. Peripheral blood lymphocytes were taken as G-banding chromosomal specimens and the karyotype was analyzed as a result of 60 metaphase cells, each of which had three translocations involving six chromosomes 2,3; 6,15; 7,14 Karyotype can be expressed as 46, XY, t (2; 3) (q37; q25), t (6; 15) (q13; p11), t (7; 14) (q11; q13) according to the international system.
