Purpose: To disclose the association between spinocerebellar ataxia with oculomotor apraxia and high grade (7 diopters) congenital astigmatism. Methods: Single observational case report. A 39-year-old patient affected by spinocerebellar ataxia from the age of 20 was submitted to genetic and ophthalmic investigations to reach a diagnosis. Results: Genetic testing did not lead to a sure diagnosis...

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...

balint’s syndrome is a rare neurological disorder associated with bilateral parieto-occipital damage which was described by rezsö bálint in 1909.the syndrome is manifested clinically by the presence of a hemispatial negligence. the lesion is usually inside parietooccipital region bilaterally in most cases but may also be compromised angular convolutions, the dorsolateral area of the occipital l...

Aprataxin, defective in the neurodegenerative disorder ataxia oculomotor apraxia type 1 (AOA1), is a DNA repair protein that processes the product of abortive ligations, 5' adenylated DNA. In addition to its interaction with the single-strand break repair protein XRCC1, aprataxin also interacts with poly-ADP ribose polymerase 1 (PARP-1), a key player in the detection of DNA single-strand breaks...

Ataxia oculomotor apraxia type 1 (AOA1) is an autosomal recessive disease caused by mutations in APTX, which encodes the DNA strand-break repair protein aprataxin (APTX). CoQ10 deficiency has been identified in fibroblasts and muscle of AOA1 patients carrying the common W279X mutation, and aprataxin has been localized to mitochondria in neuroblastoma cells, where it enhances preservation of mit...

Ataxia-telangiectasia-like disorder 1 (ATLD1) is a rare neurodegenerative associated with early onset ataxia and oculomotor apraxia. The genetic determination of ATLD1 mutation in the MRE11 gene (meiotic recombination 11 gene), which causes DNA-double strand break repair deficits. Clinical features patients resemble those telangiectasia (AT), slower progression milder presentation. Main symptom...

BACKGROUND Ataxia with oculomotor apraxia type 2 (AOA2) is an autosomal recessive disease caused by SETX mutations in 9q34 resulting in cerebellar ataxia in association with peripheral neuropathy, cerebellar atrophy on imaging, an elevated alpha-fetoprotein (AFP) serum level, and occasional oculomotor apraxia. OBJECTIVE To describe the clinical and molecular findings of 7 patients with a clin...

Dear Editor, Ataxia with oculomotor apraxia type I (AOA1) is a recessively inherited ataxic disorder that is characterized clinically by the childhood onset of progressive cerebellar ataxia, oculomotor apraxia (OMA), and peripheral axonal sensorimotor neuropathy.1 Dystonia, chorea, and cognitive impairment are commonly associated symptoms, and hypoalbuminemia and hypercholesterolemia are often ...
