Biography

Professional Background

Neurogenetic disorders, including myotonic dystrophy; therapeutics, including antisense approaches. Myotonia is a state of hyperexcitability in muscle fibers in which a voluntary contraction or electromechanical stimulation can provoke trains of repetitive action potentials. This causes delay in relaxation after a muscle contraction. The repetitive action potentials are generated by the muscle fibers, independent of any input from the motor neuron. Myotonia is caused by dysfunction of ion channels in the muscle membrane.

Myotonic dystrophy is the most common disease that causes myotonia. Recent studies in our laboratory indicate that the myotonia in myotonic dystrophy is caused, at least in part, by reduced expression of the ClC-1 chloride channel (Mankodi, et al, Molecular Cell, July 2002).

Several strains of mice with myotonia have been isolated. All spontaneous mutations that cause myotonia in mice are allelic. These strains are called "adr", for arrested development of righting response (i.e., the mice are slow to regain their upright posture after being tipped on their side). Adr strains have mutations in the murine Clcn1 gene, similar to the mutations that cause human generalized myotonia congenita.
