Intellectual disability-coarse face-macrocephaly-cerebellar hypotrophy syndrome

Intellectual disability-coarse face-macrocephaly-cerebellar hypotrophy syndrome is a rare, genetic, central nervous system malformation syndrome characterized by early-onset, progressive, severe cerebellar ataxia associated with progressive, moderate to severe intellectual disability, global developmental delay, progressively coarsening facial features, relative macrocephaly and absence of seizures. Sensorineural hearing loss may be associated. Neuroimaging reveals cerebellar atrophy/hypoplasia.
