Translocation

Translocation means a change in location. It usually refers to genetic translocations, in which part of a chromosome is transferred to another chromosome. This type of translocation results in changed and often flawed chromosomes. In another type of translocation, two chromosomes will trade pieces with each other.

Genetic translocations can cause serious disorders, including a type of chronic myelogenous leukemia.
