Spinal and Bulbar Muscular Atrophy (SBMA) is an X-linked degenerative disorder of the neuromuscular system that is caused by an expanded CAG/polyglutamine (polyQ) tract within the Androgen Receptor (AR) gene. This mutation causes progressive muscle weakness and atrophy in men. Here, we report the establishment of the first SBMA disease-specific human embryonic stem cell (hESC) line in the NIH hESC registry, UM197-1. UM197-1 exhibits pluripotency, the ability to differentiate into three germ layers in vitro, and provides a new cellular model system to study SBMA disease pathogenesis.
