In less severe cases, termed "ataxia-telangiectasia variants", there is retention of some ATM kinase activity due to either expression of very low levels of normal ATM protein (from splice site mutations) or expression of mutant ATM (from missense …
WebThe ATM gene product, ATM kinase, is involved in the detection of DNA damage and plays an important role in cell cycle progression. Biallelic, pathogenic (disease-causing) variants affecting both ATM alleles are required to develop ataxia-telangiectasia. Typically, one pathogenic variant is inherited from each parent. WebMar 29, 2024 · In addition, ATM mutations may allow cells to die inappropriately, particularly in the cerebellum (the part of the brain involved in coordinating movements). People who have mutations in one copy of the ATM gene, particularly those who have at least one family member with ataxia-telangiectasia, may be at an increased risk of developing breast ...
WebBackground: Despite the fact that heterozygosity for a pathogenic ATM variant is present in 1%-2% of the adult population, clinical guidelines to inform physicians and genetic counsellors about optimal management in that population are lacking.
