Tubular aggregate myopathy (TAM) is a hereditary muscle disorder characterized by the presence of tubular aggregates, abnormal structures in the skeletal muscle. It has been reported that activating mutations in STIM1 and ORAI1 cause TAM. ORAI1 encodes a subunit of calcium release-activated calcium (CRAC) channel, and STIM1 encodes a Ca2+ sensor that controls CRAC channels.
