  • Title: [Human chromosome polymorphism and disordered reproductive function. I. Routine chromosome variants].
    Author: Tsvetkova TG, Iankova MF.
    Journal: Genetika; 1979; 15(10):1858-69. PubMed ID: 499804.
    Abstract:
    Routine polymorphic variants of chromosomes of 58 married couples with reproductive failure (two or more spontaneous abortions, stillbirths and malformed children) and 48 control couples, having two or more normal children and no spontaneous abortions and stillbirths, were investigated by conventional staining technique. Extreme variants of chromosomes 1, 9, 16, 17, 13--15, 21--22 and Y were found in 17.2% of subjects with reproductive loss and in 15.6% of control individuals. No significant differences in frequencies of scored routine variants were noted between married couples with reproductive failure and couples with normal reproduction.
