What are ATM mutations?
Mutations in the ATM gene are found at relatively low frequencies in sporadic cancers. According to COSMIC, the Catalogue Of Somatic Mutations In Cancer, the frequencies with which heterozygous mutations in ATM are found in common cancers include 0.7% in 713 ovarian cancers, 0.9% in central nervous system cancers, 1.9% in 1,120 breast cancers, 2.1% in 847 kidney cancers, 4.6% in colon cancers, 7.2% among 1,040 lung cancers and 11.1% in 1790 hematopoietic and lymphoid tissue cancers. Certain kinds of leukemias and lymphomas, including mantle cell lymphoma, T-ALL, atypical B cell chronic lymphocytic leukemia, and T-PLL are also associated with ATM defects. A comprehensive literature search on ATM deficiency in pancreatic cancer, that captured 5,234 patients, estimated that the total prevalence of germline or somatic ATM mutations in pancreatic cancer was 6.4%. ATM mutations may serve as predictive biomarkers of response for certain therapies, since preclinical studies have found that ATM deficiency can sensitise some cancer types to ATR inhibition.
What is the role of ATM in cell cycle?
ATM plays a role in cell cycle delay after DNA damage, especially after double-strand breaks (DSBs). ATM is recruited to sites of double strand breaks by DSB sensor proteins, such as the MRN complex. After being recruited, it phosphorylates NBS1, along other DSB repair proteins.

What is ATM in cancer?
ATM is one of the DNA repair genes frequently hypermethylated in its promoter region in various cancers (see table of such genes in Cancer epigenetics ). The promoter methylation of ATM causes reduced protein or mRNA expression of ATM.
What are the risks of heterozygous mutations?
People who carry a heterozygous ATM mutation have increased risk of mainly pancreas cancer, prostate cancer, stomach cancer and invasive ductal carcinoma of the breast. Homozygous ATM mutation confers the disease ataxia–telangiectasia (AT), a rare human disease characterized by cerebellar degeneration, extreme cellular sensitivity to radiation and a predisposition to cancer. All AT patients contain mutations in the ATM gene. Most other AT-like disorders are defective in genes encoding the MRN protein complex. One feature of the ATM protein is its rapid increase in kinase activity immediately following double-strand break formation. The phenotypic manifestation of AT is due to the broad range of substrates for the ATM kinase, involving DNA repair, apoptosis, G 1 /S, intra-S checkpoint and G 2 /M checkpoints, gene regulation, translation initiation, and telomere maintenance. Therefore, a defect in ATM has severe consequences in repairing certain types of damage to DNA, and cancer may result from improper repair. AT patients have an increased risk for breast cancer that has been ascribed to ATM's interaction and phosphorylation of BRCA1 and its associated proteins following DNA damage.
What are the domains of the KD kinase?
The three domains FAT, PRD and FATC are all involved in regulating the activity of the KD kinase domain. The FAT domain interacts with ATM's KD domain to stabilize the C-terminus region of ATM itself. The FATC domain is critical for kinase activity and highly sensitive to mutagenesis.
