The Philadelphia chromosome, discovered in 1969 in the city of the same name, is found in all patients with CML. It appears under the microscope as a loss of genetic material on chromosome 22, but actually is a consequence of a balanced exchange of DNA between chromosomes 9 and 22 which produces an abnormal gene which in turn produces an abnormal protein called bcr/abl. The bcr/abl protein signals cell growth which is not inhibited by normal mechanisms by which the body regulates the numbers of circulating cells. It is the abnormal bcr/abl which is responsible for the signs and symptoms experienced by patients with CML. With rare exceptions, the cause of the development of the mutation is not known.
