Muscular dystrophies are a diverse group of inherited muscle disorders with a wide range of clinical manifestations from a severe form with early onset and early death to adult forms with later onset and minimal clinical manifestation that do not affect life-span. Overlapping clinical symptoms and the multitude of genes that need to be analyzed for an accurate characterization make the diagnosis hard. In next-generation sequencing era, a lot of used assay in molecular diagnostics must be taken into consideration for muscular dystrophy diagnosis. However, for more accurate diagnosis, muscle protein expressions analysis may have prognostic value. In this chapter, we present the most important clinical and laboratory findings in the most common forms of muscular dystrophies and molecular diagnostic approaches for a more accurate diagnosis.
