Balanced translocation in mother leading to interchange trisomy 21?
Genet Couns.
2010.
Abstract
We report an unusual balanced translocation involving chromosomes 4 and 21 in a lady who had Down syndrome in her previous child. The most plausible explanation for this event is the 3:1 segregation of chromosomes at meiosis in her gametes leading to interchange trisomy 21.
