Autosomal recessive cerebellar ataxia is heterogeneous inherited neurodegenerative disorders with more than 70 involved genes. The development of next generation sequencing opens a new window in rapid diagnosis of such heterogeneous condition in medical genetics laboratories. Here, we present ADCK3; del.CD (229-230) mutation in an Iranian consanguineous family with three cerebellar ataxic boys using whole exome sequencing. The mutation was predicted pathogenic and all the affected individuals were homozygous for the variant. Although, the ADCK3 was previously reported as one of the master genes of ARSC, our mutation was novel as has been not previously reported in dbSNP or literature.
