ATM mutations in B-cell chronic lymphocytic leukemia.

Abstract excerpt

Mutations in the ATM gene located on the long arm of chromosome 11 at 11q22-23 cause ataxia-telangiectasia, an autosomal recessive disorder that is associated with increased incidence of malignancy and, particularly, lymphoid tumors. A role for ATM in the development of sporadic T-cell chronic leukemias is supported by the finding of loss of heterozygosity at 11q22-23 and ATM mutations in leukemias carrying TCL-1...
