OMIM® : ⁵⁷ Stress-induced childhood-onset neurodegeneration with variable ataxia and seizures (CONDSIAS) is an autosomal recessive neurodegenerative disorder with onset in the first years of life following normal early development. Patient have cyclic episodic deterioration in response to stress, such as infection or febrile illness. The severity is highly variable: some patients develop seizures early in life that are associated with loss of developmental milestones and early sudden death in childhood, whereas others present at a later age with muscle weakness, gait ataxia, impaired speech, more subtle clinical deterioration, and cognitive decline. Neurologic involvement includes gait ataxia, cerebellar signs associated with cerebellar atrophy, generalized brain atrophy, impaired intellectual development, hearing loss, and peripheral neuropathy (summary by Ghosh et al., 2018).

MalaCards based summary : Neurodegeneration, Childhood-Onset, Stress-Induced, with Variable Ataxia and Seizures, also known as condsias, is related to ataxia and polyneuropathy, adult-onset and seizure disorder, and has symptoms including seizures An important gene associated with Neurodegeneration, Childhood-Onset, Stress-Induced, with Variable Ataxia and Seizures is ADPRS (ADP-Ribosylserine Hydrolase). Affiliated tissues include tongue and spinal cord, and related phenotypes are hearing impairment and seizure

Disease Ontology : ¹² A neurodegenerative disease characterized by variable ataxia and seizures, has material basis in homozygous mutation in the ADPRHL2 gene on chromosome 1p34, and has symptom seizures, muscle weakness, giat ataxia, impaired speach, hearing loss, and cerebellar atrophy.

UniProtKB/Swiss-Prot : ⁷³ Neurodegeneration, childhood-onset, stress-induced, with variable ataxia and seizures: An autosomal recessive neurodegenerative disorder characterized by pediatric onset of progressive brain atrophy, developmental regression, and seizures in association with periods of stress, such as infections.
