Effect of the Kennedy Mutation of the Androgen Receptor on Gene Expression in Neuroblastoma Cells
Kennedy’s syndrome (X-linked bulbar and spinal muscular atrophy) is an X-linked disorder characterised by sensory and lower motor neurone degeneration.1,2,3 The discovery of a mutation in the androgen receptor (AR) gene in Kennedy’s syndrome reinforced the hypothesis that an X-linked factor might be involved in the disease process of Amyotrophic Lateral Sclerosis (ALS), because of the prevalence of the disease in males, (ratio 1.6:1). This mutation, which is tightly linked with the disease phenotype, consists of an increased number of CAG repeats present in the first exon of the AR gene, encoding a polyglutamine chain.
