Familial t(X;2) (p223;q323) with partial trisomy 2q and male and female balanced carriers.
A familial t(X;2) (p223;q323) is responsible for partial trisomy 2q in the proposita, a 3-year-old girl with severe mental retardation and hypotrophia. It is present in the balanced state in the mother, two daughters, and one son. X-replication was studied after BUDR incroporation and acridine orange staining. The reproductive impairment of balanced X/autosome translocations is discussed.
