Metabolic alterations in spinal and bulbar muscular atrophy.

Abstract excerpt

Spinal and bulbar muscular atrophy (SBMA) is a rare, X-linked neuromuscular disease characterised by lower motor neurons degeneration, slowly progressive myopathy and multisystem involvement. SBMA is caused by trinucleotide repeat expansion in the first exon of the androgen receptor (AR) gene on chromosome X that encodes a polyglutamine (polyQ) tract in the AR protein. Disease onset occurs between 30-60 years of...
