Aneuploidy in the placenta is a pathological factor associated with adverse pregnancy outcomes and impaired placental function. According to studies, chromosomal abnormalities confined to placental tissue occur in approximately 1-2% of pregnancies, but they do not always affect fetal development. The placenta is a vital organ for fetal development and is composed primarily of trophoblasts derived from the outer layer of the embryo (trophectoderm).
