  • Look Inside

Spinal and bulbar muscular atrophy (SBMA) is an X-linked late-onset motor neuron disease characterized by proximal muscle atrophy, weakness, contraction fasciculations, and bulbar involvement. Heterozygous female carriers are usually asymptomatic. A specific treatment for SBMA has not been established. The molecular basis of SBMA is the expansion of a trinucleotide CAG repeat in the first exon of the androgen receptor (AR) gene, which encodes the polyglutamine (polyQ) tract.
