Since muscle calcium dysfunctions are common in DMD (Walther et al, 2000; Sparks et al, 2007; Maguire et al, 2019), we investigated the muscle amount of calcium channel proteins as transient receptor potential canonical 1 (TRPC1) and vanilloid receptor 1 (VR‐1). This evidence concerns the gene TRPC1 and Duchenne muscular dystrophy.
