Background: Ataxia with oculomotor apraxia type 1 (AOA1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (APTX) gene encoding for the APTX protein. Methods: In this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and AOA, with increased cholesterol concentration and decr...
Aborted DNA ligation events in eukaryotic cells can generate 5'-adenylated (5'-AMP) DNA termini that can be removed from DNA by aprataxin (APTX). Mutations in APTX cause an inherited human disease syndrome characterized by early-onset progressive ataxia with ocular motor apraxia (AOA1). APTX is found in the nuclei and mitochondria of eukaryotic cells. Depletion of APTX causes mitochondrial dysf...

Hereditary ataxias are a clinically and genetically heterogeneous family of disorders defined by the inability to control gait and muscle coordination. Given the nonspecific symptoms of many hereditary ataxias, precise diagnosis relies on molecular genetic testing. To this end, we conducted whole-exome sequencing (WES) on a large consanguineous Iranian family with hereditary ataxia and oculomot...
Mitochondrial aprataxin (APTX) protects the mitochondrial genome from the consequence of ligase failure by removing the abortive ligation product, i.e. the 5'-adenylate (5'-AMP) group, during DNA replication and repair. In the absence of APTX activity, blocked base excision repair (BER) intermediates containing the 5'-AMP or 5'-adenylated-deoxyribose phosphate (5'-AMP-dRP) lesions may accumulat...

Early-onset ataxia with ocular motor apraxia and hypoalbuminemia (EAOH) is a neurodegenerative disorder caused by mutation in the aprataxin (APTX)-coding gene APTX, which involved DNA single-strand break repair (SSBR). The neurological abnormalities associated EAOH are similar to those observed patients ataxia-telangiectasia. However, immunological have not been described. In this study, we rep...
ataxia oculomotor apraxia1(aoa1) is the most frequent cause of autosomal-recessive cerebellar ataxia in japan,but it is reported from all of the world. the presentation is nearly identical to that of at without the non-neurological features,and accounts for up to 10% of autosomal-recessive cerebellar ataxias.gait imbalance and dysarthria are typical presenting features,oculomotor apraxia typica...
OBJECTIVES/BACKGROUND Ataxia with oculomotor apraxia defines a group of genetically distinct recessive ataxias including ataxia-telangectasia (A-T, ATM gene), ataxia with oculomotor apraxia type 1 (AOA1, APTX gene) and type 2 (AOA2, SETX gene). Although, a few unique clinical features differentiate each of these forms, the patients also share common clinical signs, such as the presence of cereb...
Ataxia-oculomotor apraxia syndrome 1 is an early onset cerebellar ataxia that results from loss of function mutations in the APTX gene, encoding Aprataxin, which contains three conserved domains. The forkhead-associated domain of Aprataxin mediates protein-protein interactions with molecules that respond to DNA damage, but the cellular phenotype of the disease does not appear to be consistent w...
