The INMR studies the causes, consequences and therapies for patients with inherited neuromuscular disorders. Neuromuscular disorders encompass a large group of inherited disorders that cause abnormalities in the structure and function of our skeletal muscle or nerves. These disorders can have devastating consequences for affected children, often resulting in the loss of the ability to walk or perform activities of daily living, and many are life-limiting. 

Our research programs ranges from Gene Discovery using latest technologies in next generation sequencing to identify new causes of inherited muscle and nerve disorders, fundamental neurochemistry trying to unlock the mechanism underlying disease, through to clinical trials to evaluate new therapies for our patients.

To study disease mechanism a new form of myopathy using CRISPR/Cas9-mediated fluorescent labelling, live-cell microscopy and protein-interaction studies.

Primary supervisor: Sandra Cooper

As part of our large program in translational genomics, we have identified a new gene that causes an early–onset myopathy in children. The gene is an oxidoreductase, and is previously unstudied in the published literature. It is rare to find something utterly uncharacterised in 2016, and this gene is essential for life.  This gene introduces altered redox as a new pathway in the myopathies, with many similarities to features of neurodegenerative disorders. We want to study how this protein responds to oxidative stress, and find which substrates it regulates the redox state of that cells cannot live without.
