What does ATM gene stand for?

What does ATM gene stand for?

The name ATM stands for “Ataxia-Telangiesctasia Mutated.” The ATM gene is located on chromosome 11. ATM helps to control cell growth and repair damaged DNA .

What is ATM diagnosis?

Ataxia-telangiectasia is a rare inherited disorder that affects the nervous system, immune system, and other body systems. This disorder is characterized by progressive difficulty with coordinating movements (ataxia) beginning in early childhood, usually before age 5.

What is ATM in breast cancer?

Abstract. The ATM gene is mutated in the syndrome, ataxia-telangiectasia (AT), which is characterized by predisposition to cancer. Patients with AT have an elevated risk of breast and brain tumors Carrying mutations in ATM, patients with AT have an elevated risk of breast and brain tumors.

How rare is the ATM gene?

A-T is rare. It is estimated that A-T affects 1 in 40,000 to 1 in 100,000 people. The chance that a person is a carrier of a single ATM gene mutation is about 1%, or 1 in 100.

Is ATM a tumor suppressor gene?

Although ATM is rightly considered to be a tumour suppressor, ATM signalling can also be advantageous to cancer cells, particularly in resistance to radio- and chemotherapeutic treatment.

What is the life expectancy of someone with ataxia telangiectasia?

Ataxia telangiectasia is a rare, multiorgan neurodegenerative disorder with enhanced vulnerability to cancer and infection. Median survival in two large cohorts of patients with this disease, one prospective and one retrospective, is 25 and 19 years, with a wide range.

Is ATM the same as BRCA?

ATM is the fifth DNA repair gene, together with BRCA1, BRCA2, TP53 and CHEK2 shown to be involved in breast cancer predisposition. Whereas BRCA1, BRCA2 and TP53 are associated with high risks of breast cancer, ATM and CHEK2 are associated with more modest risks (Antoniou and Easton, 2006, this issue).

What cancers are associated with ATM mutation?

Mutations in one copy of the ATM gene can increase the chance for you to develop certain types of cancer in your lifetime. You have an increased chance to develop female breast cancer (about 2-4 times higher than the average woman), pancreatic cancer, prostate cancer, and possibly other cancers.

What is ATM in biochemistry?

The ataxia-telangiectasia mutated (ATM) protein kinase is a master regulator of the DNA damage response, and it coordinates checkpoint activation, DNA repair, and metabolic changes in eukaryotic cells in response to DNA double-strand breaks and oxidative stress.
