Mutations were found in the DMD gene of the five suspected DMD patients and in four non-DMD/BMD patients with an initial diagnosis of limb-girdle muscular dystrophy (LGMD) of unknown etiology including the following: one FKRP, one CAV3, and two likely causative pairs of variations in the CAPN3 gene of two patients (Table 7). Here, CAPN3 is linked to Duchenne muscular dystrophy.
