For example, mutations in MRE11, TDP1 and aprataxin (APTX) result in neurodegenerative disorders such as A-T like disease (ATLD) [48], spinocerebellar ataxia with axonal neuropathy (SCAN1) [49], and ataxia-oculomotor apraxia-1 [50, 51] respectively. The gene discussed is APTX; the disease is ataxia-telangiectasia-like disorder.
