Progressive encephalopathy with amyotrophy and optic atrophy (PEAMO) is a severe autosomal recessive neurodegenerative disorder characterized by delayed development with hypotonia apparent in infancy and subsequent motor regression. Most affected individuals are unable to or lose the ability to sit and show distal amyotrophy and weakness of all 4 limbs. The patients are cognitively impaired and unable to speak or have severe dysarthria. Additional features include optic atrophy, thin corpus callosum, and cerebellar atrophy (Sferra et al., 2016).
