Balanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report

One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16; 6) (p12; q26) and 46, XY, t (16; 6) (p12; q26) in both partners, which induced such pregnancy complications. Chromosomal balanced translocation is one of the most common causes of recurrent spontaneous abortions (RSA). In such cases prenatal diagnosis (PND) during the 16th week of gestation is strongly recommended.
