A liveborn infant with tetraploidy.
We report on an 22-month-old white girl with tetraploidy who is growing well, but who is extremely delayed in psychomotor development. When counseling parents it is important to realize that, although quite rare, tetraploid individuals can be born alive and live for at least 22 months. The implications are also relevant to prenatal diagnosis.
