最常见的人类X染色体的结构异常是长臂等臂X染色体,以及X染色体与常染色体之间的易位。关于idic(X)染色体结构异常的病例较为罕见。国外Chapella等曾有研究,国内周氏等首次报道了有关idic(X)染色体结构异常的病例。
The most common structural abnormalities of the human X chromosome are the arm-arm X-chromosome and the translocation between the X-chromosome and the autosome. There are rare cases of idic (X) chromosomal structural abnormalities. Chapella and other foreign countries have been studied, such as domestic Zhou for the first time reported on the idic (X) chromosome structure abnormalities.
