染色体之间的相互易位是常见的染色体结构畸变之一。平衡易位以携带者表现,临床表现往往正常,而流产或生出染色体异常的子女是这类携带者最突出的遗传效应。我们发现的染色体6/8平衡易位一例,经查阅国内外资料,仅见“中国人类染色体异常目录”中,记载了一例为6/8易位,但其断裂点为6 q15,8 q24;而我们发 Mutation between chromosomes is one of the common chromosomal structural aberrations. Balanced translocation to carrier performance, clinical manifestations are often normal, and abortion or give birth to children with chromosomal abnormalities is the most prominent carrier effect of these carriers. We found a chromosome 6/8 equilibrium translocation of a case, after reviewing domestic and foreign data, only to see “Chinese human chromosome abnormalities directory”, recorded a case of 6/8 translocation, but the break point of 6q15,8q24; and We send
