PGDlab : For Patients : What is PGD : Q & A

A member of a couple may carry a balanced translocation (exchange of chromosome material between two or more chromosomes), a Robertsonian translocation (the joining of two chromosomes) or other structural rearrangements. This increases the risk for a pregnancy with an unbalanced chromosome complement, which can cause birth defects, mental retardation, and/or miscarriage. PGD for structural chromosome rearrangements allows couples to decrease these risks and to increase the chance of a healthy ongoing pregnancy.

I want to learn more about PGD for structural chromosome rearrangements.
