Neuromuscular diseases are rare diseases for which significant progress has been made in the context of diagnosis thanks to advances in molecular techniques, but the intimate mechanisms of lesion formation remain poorly understood. Advances in cellular and molecular biology, the development of a few animal models, such as transgenic mice, which make it possible to mimic human pathology have made it possible to better understand the physiopathology of these diseases. However, they still do so very imperfectly and incompletely, making it even more necessary than ever to study diseased human muscle tissue to find new avenues of research or to confirm results obtained by experimentation.

The purpose of this collection of tissue samples for neuro-muscular purposes is to collect such samples under the best conditions in order to promote basic and translational research on muscle diseases.

This is why the CHU de Bordeaux wishes to keep the remainders of samples taken as part of the treatment to constitute a collection of biological samples and associated data kept according to quality standards and in compliance with the regulations in force.

The "COLMYONEU" project is a project to collect leftover frozen neuromuscular biopsy samples from patients taken as part of their health care at the Bordeaux University Hospital for neuromuscular disease.

Its main objective is to store, under the conditions of the CRB standard, residual biological samples from patients with neuromuscular symptoms.
