在2 703例遗传咨询门诊病例中检出9号染色体臂间倒位21例,将本组inv(9)的频率与普通群体inv(9)的频率作比较,并通过对伴有其它性状的inv(9)家系的分析,讨论了inv(9)的遗传效应问题。 Abstract: Twenty one cases of pericentric inversion of chromosome 9 were found in 2703 patients asking genetic counseling. The percentage of inv(9) in this group was compared with that in normal population. Two special pedigrees with inv(9) were analyzed and the genetic effects of inv(9) were discussed.
