Proteins in this family are mostly from animals. The only characterized protein is LisH domain-containing protein ARMC9, which is localized to the basal body of a cilium and is upregulated during ciliogenesis. Mutations in the ARMC9 gene cause Joubert Syndrome, a recessive neurodevelopmental disorder characterized by hypotonia, ataxia, abnormal eye movements, and variable cognitive impairment [].
