Brief summary: Duchenne muscular dystrophy is a rare progressive X-linked neuromuscular disease, caused by mutation in the dystrophin gene, leading to progressive muscle degeneration, loss of specific functional milestones, severe respiratory and cardiac impairment. Improved standards of care and the regular early use of glucocorticoid treatment have changed the natural history of the disease, affecting both survival and the time of loss of functional milestones. More recently, there has been increasing evidence of an additional benefit from new therapeutical approaches based on mechanisms targeting specific type of mutation; therefore, it has become mandatory to obtain more detailed long-term information about the patterns of progression related to different genotypes. The aim of this project is to better define the natural history of Duchenne musculare Dystrophy patients and to understand clinical and motor functional trajectories defining a more specific genotype/phenotype characterization according to the type of mutation.

Detailed description: Duchenne muscular Dystrophy is a progressive disorder affecting one in 3600-5000 live male births, leading to a progressive loss of specific functional milestones.

Over the past two decades, the development of new outcome measures has allowed a better definition of the natural history of the disease. Recently, there has been increasing evidence of benefit from new therapeutical approaches based on inflammatory, fibrotic and genetic mechanisms targeting specific type of mutations. The changes are better observed after the first year of treatment but as it is not possible to maintain placebo for such a long time, it has become mandatory to have natural history data for comparison. As there is increasing evidence that specific groups of mutations may have different progression of the disease, a few studies have been performed to study longitudinal functional changes in Duchenne patients with different types of mutations (deletion, duplication, small mutations) and in the subgroups eligible for skipping individual exons, focusing on those skipping 44, 45, 51 and 53 . Our groups has been involved in national and international efforts to define the trajectories of progression according to phenotypes, reporting functional changes using different measures such as the six minute walking test , North Star Ambulant Assessment in ambulant patients, and in non-ambulant patients, using the Performance of Upper limb test 2.0 and respiratory function.

The study will involve all patients with genetically confirmed Duchenne muscular Dystrophy diagnosis currently in follow up in 4 italian centers.

This research aims to provide more information about natural history in Duchenne patients, including genetic, functional motor, cardiological and respiratory data collection to define a better and complete genotype and phenotype correlation, not only in ambulant but also in not ambulant patients.
