**3.7 Autosomal recessive cerebellar ataxia**

Autosomal recessive cerebellar ataxias (ARCAs) are a part of the diverse category of hereditary ataxias. They often start young and are marked by degeneration of the cerebellum and spinal cord [24, 26, 29–31]. **Table 1** displays the most typical ARCAs that have been genetically identified, wherein we note that ataxia telangiectasia and FRDA are the two most prevalent forms in white children [24, 31, 44, 45].
