Molecular cytogenetic characterization of mosaicism for a small supernumerary marker chromosome derived from chromosome 7 in the male partner of a phenotypically normal couple with repeated spontaneous abortions

[[abstract]]A non-consanguineous infertile couple was referred for genetic counseling because of two spontaneous abortions. The couple had two natural conceptions ending in spontaneous abortions. The wife was 36 years old, and the husband was 41 years old. The woman did not have any child and had undergone assisted reproductive technology because of infertility. The urological, gynecological and infectious investigations of the couple revealed normal results. Cytogenetic analysis of the couple' peripheral bloods revealed a karyotype of 46,XX in the wife and a karyotype of 47,XY+mar[14]/46,XY[26] in the husband
