Unstable translocations: a new case?
A female patient with Down syndrome due to unbalanced Robertsonian translocation (14;21) is reported. A different Robertsonian translocation involving a chromosome no. 14 was observed in her father, who was a carrier of a balanced Robertsonian t(13;14), while the maternal karyotype was normal. Hypotheses about the origin of the translocation in the daughter are discussed.
