Recently, mutation in <i>SQSTM1</i> was also found to cause a progressive childhood-onset cerebellar ataxia. We describe here a case of progressive childhood-onset cerebellar ataxia with vertical supra nuclear gaze palsy with no family history and a normal magnetic resonance imaging (MRI) of brain. The clinical exome sequencing in this patient showed a homozygous mutation in <i>SQSTM1</i>. This case highlights the importance of next-generation sequencing in the diagnosis of inherited ataxia syndromes. <i>SQSTM1</i> mutation should be considered in the differential diagnosis in a patient with both cerebellar ataxia and ophthalmological manifestations.</p>
