Creatine kinase For the diagnosis of<unk> , the following tests/exams are done: * Lab study (CK levels) * Muscle MRI and especially whole body muscle MRI has recently been used to describe muscle abnormalities in patients with primary laminin-α2 (merosin) deficiency subtype of<unk> . * EMG * Genetic testing (different types of<unk> es) The subtypes of<unk>  have been established through variations in multiple genes. Phenotype, as well as, genotype classifications are used to establish the subtypes, in some literature. One finds that<unk> es can be either autosomal dominant or autosomal recessive in terms of the inheritance pattern, though the latter is much more common Individuals who suffer from<unk>  fall into one of the following types: Differential diagnosis The DDx of<unk> , in an affected individual, is as follows (non-neuromuscular genetic conditions also exist): * Metabolic myopathies * Dystrophinopathies * Emery-Dreifuss muscular dystrophy
Congenital muscular dystrophy
Spinal muscular atrophy
Congenital myopathy
Congenital distal spinal muscular atrophy
Chondrodystrophy
Spinal muscular atrophies
Muscular dystrophy
Infantile neuroaxonal dystrophy
