  • Abstract
  • Look Inside

 Spinal and bulbar muscular atrophy (SBMA) is an adult form of hereditary lower motor neuron disease characterized by proximal dominant muscular weakness in the limbs and bulbar involvement with contraction fasciculation. It also exhibits a mild and partial androgen insensitivity. SBMA is caused by the expansion of a polymorphic CAG trinucleotide repeats within the coding region of the androgen receptor gene, resulting in a polyglutamine stretch expansion in the androgen receptor protein.
