Genetic Counseling and Philadelphia

Philadelphia: A great place to study Genetics! The only city with a chromosome named for it!

Philadelphia Chromosome

Several types of leukemia are associated with a reciprocal translocation between chromosome 9 and chromosome 22. Here, chromosome 22 is called the Philadelphia chromosome).

This translocation is found only in tumor cells and indicates that a patient has chronic myelogenous leukemia (CML), a condition in which the cells that produce blood cells for the body grow uncontrollably, leading to cancer.
