Myotubular myopathy is an X-linked genetic disease affecting 1 in every 50,000 newborn boys. It is caused by mutations in the MTM1 gene encoding myotubularin, a protein involved in the development and function of muscle cells. It is characterized by extreme muscle weakness and respiratory failure, with an estimated 50% mortality rate by 18 months of age.
