X-linked adrenoleukodystrophy (ALD) usually presents in childhood as severe cerebral demyelination accompanied by axonal loss or in adults as a progressive spinal cord syndrome (adrenomyeloneuropathy). Rarely, patients present with adult onset spinocerebellar ataxia. We performed mutation analysis in a family with several members who had this rare phenotype and identified a single nucleotide deletion in exon 2 of the ALD gene. This is the first mutation analysis to be reported in this unusual phenotypic variant of ALD and the first deletion to be reported in exon 2.
