PubMedID- 22125427 Spinocerebellar ataxia with axonal neuropathy 1 (scan1) is caused by autosomal recessive mutations in the gene encoding tyrosyl-dna phosphodiesterase 1 (tdp1), a protein required for the repair of dna single-strand breaks that arise independent of dna replication from abortive topoisomerase 1 activity or oxidative stress.

PubMedID- 20687496 Spinocerebellar ataxia with axonal neuropathy (scan 1) is an autosomal recessive disorder caused by a specific point mutation (c.1478a>g, p.h493r) in the tyrosyl-dna phosphodiesterase (tdp1) gene.
PubMedID- 23104055 Tdp1 deficiency is linked to the neurological disease spinocerebellar ataxia with axonal neuropathy (scan1)31,32 and tdp2 activity on 3′-linked topoisomerase adducts appears important in the absence of tdp1 (ref.
