For example, ordering specific genetic study of D4Z4 gene and Multiplex Ligation-dependent Probe Amplification (MLPA) of dystrophin gene are the primary requested evaluation tests for a patient with typical phenotype of Fascioscapulohumeral muscular dystrophy (FSHD) and Duchenne muscular dystrophy (DMD) respectively. Here, DMD is linked to Duchenne muscular dystrophy.
