These myopathies, although caused by mutations in genes associated with the regulation of the N-linked glycosylation pathway, also seem to involve pathways comprising proteins participating in the regulation of Ca2+ homeostasis, including STIM1 (Funk et al. 2013; Bauché et al. 2017; Gang et al. 2022; Brande et al. 2023). The gene discussed is STIM1; the disease is myopathy.
