STIM1 and myopathy: Not only are they present in muscle biopsies from patients with mutations in proteins involved in the glycosylation pathway (1–3,5,8,9) but are also implicated in myopathies resulting from STIM1 and ORAI1 mutations (30–32), and are present in muscle from Caveolin1−/− and Caveolin2−/− mice (29).
