NCIt definition : Human ATM wild-type allele is located within 11q22-q23 and is approximately 143 kb
in length. This allele, which encodes serine-protein kinase ATM protein, plays a critical
role in cell cycle checkpoint signaling pathways required for cellular response to
DNA damage and maintenance of genomic stability. Defects in the ATM gene cause ataxia
telangiectasia and contribute to certain cancers such as T-cell acute lymphoblastic
leukemia, B-cell chronic lymphocytic leukemia and B-cell non-Hodgkin lymphomas.;
