title: A cytogenetic study of five rare karyotypes.
abstract: The results of chromosome analysis of 5 cases from our genetic counseling showed that among these patients, 4 had two or more repeated spontaneous abortions. Structural abnormalities with the karyotypes 46, XX, t(1;11)(q42;q13), 46, XY, t(17;19)(q21;p13.3), 46, XY, t(4;5)(p13;q35) were reported for the first time in the literature abroad. The karyotypes 46, XX, t(16;18)(q24;q21), 46,XX, t(3;8)(p21;q24.3) were reported for the first time in the literature at home. A discussion is made on the origin of chromosome aberration and the cause of repeated spontaneous abortions.
