For example, mutations in the gene encoding ATM (ataxia telangiectasia mutated) can lead to the development of AT or breast cancer (Renwick et al., 2006; Choi et al., 2016), while mutations in the gene encoding FUS (fused in sarcoma) cause ALS and sarcomas (Ward et al., 2014). The gene discussed is ATM; the disease is sarcoma.
