Nemaline, or rod, myopathies are types of congenital myopathies characterised by rod-like structures in muscle cells. They are accompanied by symptoms such as muscle weakness, as well as breathing and eating problems. Nemaline myopathies are rare conditions, affecting around one in every 50,000 people. They are caused by changes in several genes, including ACTA1, NEB, TPM3, TPM2, TNNT1 and more.
Developing treatments for these conditions requires a thorough understanding of the natural causes and progression of the condition. Given the number of different genetic changes that can cause nemaline myopathies it’s important to document these to help shape future research studies and clinical trials. This is why we have observational studies called natural history studies. Through these studies, researchers and clinicians can have access to invaluable information about people’s conditions, the progression of their condition, and if/how they are managing it.
