A case of down¡¯s syndrome in twins of unlike sex


Abstract
Down syndrome is a chromosome related desease that shows mental retardation, growth retardation and many other signs such as defects in the face, hands and skin. Down syndrome is very uncommon in dizygotic twins, especially in twins with different sex. This twin¡¯s chromosomal analysis shows both twins with trisomy 21, but the parents¡¯ chromosomal analysis is normal. A 30 year old infertile woman who became pregnant via ICSI(intracytoplasmic sperm injection) has shown dizygotic twins with different sex to have Down syndrome and therefore it is being reported along with simple documents.
