Abstract
In this study, in order to promote chromosome abnormality carriers eugenics, three patients with adverse pregnancy histories were examined by cytogenetics and their pedigrees further analyzed. In this retrospective study, approximately anticoagulant peripheral venous blood from the patients was collected for peripheral blood cell culture and chromosome analysis. Karyotypes were analyzed in the BEIONMED karyotype analysis system. The karyotypes of the three probands were all whole-arm translocations (WATs): case 1 (DatabaseNo.3591): 46, XY, t (7; 13) (p10; p10) dn, two years of marriage in which the spouse did not have pregnancy, with azoospermia; case 2 (Database No.3809): 46, XY, t(12; 17) (p10; q10), three spontaneous abortions within three years of marriage; case 3 (Database No.4914) 46, XX, t(2;6) (p10; q10) mat, 21ps+pat, a year of marriage without pregnancy. When the parents are carriers of WAT, the family should be considered to have a high reproductive risk, increasing the risk of producing offspring with chromosomal abnormalities. Three kinds of human chromosomal aberration karyotypes were reported for the first time providing an important basis for studying the occurrence and clinical consultation of chromosomal diseases.
