RYR1‐related myopathies are generally non‐progressive or slowly progressive and are characterized by a wide range of symptoms including mild muscle weakness, hypotonia, motor developmental delay, orthopaedic complications, including scoliosis and foot deformities, and, more rarely, to cases with wheelchair dependence and respiratory failure (Dowling et al., 2014; Jungbluth et al., 2018; Lawal et al., 2020). The gene discussed is RYR1; the disease is myopathy.
