The inability to repair damage to DNA clearly can have effects on post-mitotic neurons and cause severe CNS symptoms. Ataxia telangiectasia (A-T), ataxia oculomotor apraxia type 1 (AOA1) and spinocerebellar ataxia with axonal neuropathy (SCAN1) all show progressive neurodegeneration. While it is known that these disorders show defective DNA double or single strand break repair, the precise mechanism of the neurodegeneration is still a mystery (reviewed in McKinnon and Caldecott, 2007
). For these and other disorders like Parkinson's disease, oxidative stress may play an important role in damaging the neuronal DNA. In the case of xeroderma pigmentosum (XP), a very rare recessively inherited skin
