Ataxia, intention tremor, and hypotonia syndrome, childhood-onset

Summary

Childhood-onset ataxia, intention tremor, and hypotonia syndrome (ATITHS) is a neurodevelopmental disorder characterized by delayed walking due to ataxia, intention tremor, and hypotonia apparent from early childhood. Affected individuals have global developmental delay with mildly impaired intellectual development and speech delay or learning disabilities. Eye movement abnormalities may also be present. Brain imaging shows cerebellar atrophy in some patients (summary by Webb et al., 2021). [from OMIM]
