Abstract

Infantile neuroaxonal dystrophy is a rare neurodegenerative disorder characterized by infantile onset and rapid progression of psychomotor regression and hypotonia evolving into spasticity and dementia. Although nystagmus is a well-established neurological sign in infantile neuroaxonal dystrophy, it is mainly described as pendular and noticed in later stages of the disease.We report a 13-month-old girl with infantile neuroaxonal dystrophy harboring a compound heterozygous mutation in the PLA2G6 gene with downbeat nystagmus as the only presenting symptom. Our case indicates that downbeat nystagmus can be a rare but very early onset sign of cerebellar involvement in infantile neuroaxonal dystrophy and can anticipate the appearance of psychomotor regression and neuroradiological abnormalities.
