In contrast, multiple other limb-girdle pattern muscular dystrophies, including those with pathogenic variants in calpain-3 (CAPN3), dystrophin (DMD), and fukutin-related protein (FKRP) may have inflammatory cell infiltrates in muscle biopsy specimens yet they are typically not confused with inflammatory myopathies [13, 15]. This evidence concerns the gene FKRP and Duchenne muscular dystrophy.
