Description

This variant is denoted ATM c.8147T>C at the cDNA level, p.Val2716Ala (V2716A) at the protein level, and results in the change of a Valine to an Alanine (GTT>GCT). This variant has been observed in the compound heterozygous state in multiple individuals with atypical or later-onset ataxia telangiectasia (Hiel 2006, Verhagen 2009, Demuth 2011, Keimling 2011, M?neret 2014, Kuhm 2015, Lohmann 2015, van Os 2017). In addition, ATM Val2716Ala has been published in the heterozygous state in at least three individuals with early-onset breast cancer, one of whom also had a history of unexplained childhood onset choreoathetosis, oculocutaneous telangiectasias, and elevated serum alpha-fetoprotein (Mandigers 2011, Reiman 2011). Although this variant may express some level of kinase activity, it has been associated with reduced ATM protein expression, and transfected cells have exhibited reduced radiation-induced kinase activity (Scott 2002, Verhagen 2009, Demuth 2011, Reiman 2011). ATM Val2716Ala was not observed at a significant allele frequency in large population cohorts (Lek 2016). This variant is located in the kinase domain and the ATP-binding domain (Lavin 2004, Stracker 2013). In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, we consider ATM Val2716Ala to be pathogenic.
