Prenatal testing can be used to identify fetuses with chromosomal
abnormalities or genetic mutations that would result in the birth of an affected newborn.
The aneuploid theory was tossed aside about 50 years ago because researchers were unable to detect any chromosomal
patterns with available technology.

Further subdivision of translocation types can be made according to the exchange of chromosomal
material and are classified as: (i) reciprocal, when segments from two different chromosomes have been exchanged; or (ii) robertsonian, in five acrocentric chromosomes (13, 14, 15, 21 and 22), where long arms fuse to form a single chromosome with a single centromere.
