About this section


Fully expand this MalaCard
Genetics Home Reference:21 Ataxia with oculomotor apraxia is a condition characterized by progressive problems with movement. The hallmark of this condition is difficulty coordinating movements (ataxia), which is often the first symptom. About half of affected people have trouble moving their eyes to look side-to-side (oculomotor apraxia). People with oculomotor apraxia have to turn their head to see things in their side (peripheral) vision.

MalaCards based summary: Early-Onset Ataxia with Oculomotor Apraxia and Hypoalbuminemia, also known as ataxia-telangiectasia-like syndrome, is related to apraxia and adenocarcinoma, and has symptoms including flared eyebrows, functional anomalies of the nervous system and abnormal gait. An important gene associated with Early-Onset Ataxia with Oculomotor Apraxia and Hypoalbuminemia is PCNA (proliferating cell nuclear antigen), and among its related pathways are Chks in Checkpoint Regulation and Cell Cycle / Checkpoint Control. The compounds arginine and mitomycin c have been mentioned in the context of this disorder. Affiliated tissues include eye and skin.
