This gene encodes a member of the histidine triad (HIT) superfamily. The encoded protein may play a role in single-stranded DNA repair through its nucleotide-binding activity and its diadenosine polyphosphate hydrolase activity. Mutations in this gene have been associated with ataxia-ocular apraxia. Alternatively spliced transcript variants have been identified for this gene.[provided by RefSeq, Aug 2010] (from

258 patients were having a GBM [including 31 with a GBM with oligodendroglioma component (GBM-O)], 31 with a gliosarcoma, 13 with an anaplastic astrocytoma (AA), 12 with an anaplastic oligodendroglioma (AO), and 10 with an anaplastic oligoastrocytoma (AOA).

Aprataxin (APTX), a protein altered in the heritable neurological disorder Ataxia with Oculomotor Apraxia 1 (AOA1), acts as a DNA ligase "proofreader" to directly reverse AMP-modified nucleic acid termini in DNA- and RNA-DNA damage responses.
Williams et al., United States. In Nat Struct Mol Biol, 2011
Data suggest that mutations affecting protein folding, the active site pocket and the pivot motif underlie aprataxin dysfunction in the neurodegenerative disorder ataxia with oculomotor apraxia 1 (AOA1).
Gellera et al., Milano, Italy. In Neurogenetics, 2011
The clinical phenotype was homogeneous, irrespectively of the type and location of the APTX mutation, and it was mainly characterized by early-onset cerebellar signs, sensory neuropathy, cognitive decline, and oculomotor deficits.
The patients with early onset ataxia with ocular motor apraxia and hypoalbuminaemia homozygous for the c.689_690insT mutation(APTX) show a more severe phenotype than those with a p.Pro206Leu or p.Val263Gly mutation.
