Abstract

Using several cytogenetic technics,the etiology of 14 cases with amenorrhea was studied.The abonomal karyotypes were found in 11 cases (78.6% cases studied),inc luding 45,X (3 cases);45,X/46,X,i (Xq) (2 cases);45,X/46,XX/47,XXX (1 case);45,X /46,X,idic (X) (1 case);46,X,idic (X) (1 case);46,X del (X) (q24) (1 case);45,X/ 46,X,idic (X) (p 11.3) (1 case) and 46,XY (1 case).54.5% of these cases involve the structural rearrangement of X chromosome.The cytogenetic mechanism of the pa tients with amenorrhea,the possible relationship between karyotype and phenotype ,and the pattern of the replicate region in inactivated X chromosomes were discu ssed.
