Mitochondrial membrane protein associated neurodegeneration (MPAN) belongs to the Neuronal brain iron accumulation (NBIA) spectrum disorder. It is caused by mutation in the C19orf12 gene. A 13-y-old previously healthy girl born to non-consanguineous marriage couple presented with regression of motor and cognitive milestones and decreased vision in both eyes, since 8 y of age. Examination revealed pyramidal signs, dystonia, dysarthria and pale optic disc. Neuroimaging showed streaking of medial medullary lamina of Globus pallidus. Genetic analysis revealed a novel p. G55W in exon 3 of C19orf12 gene in homozygous state. Mitochondrial membrane protein associated neurodegeneration should be considered in any child presenting with neuronal brain iron accumulation spectrum disorder with findings of streaking of medial medullary lamina of Globus pallidus and absent retinitis pigmentosa.
