Immunodeficiency 9, also known as immune dysfunction with t-cell inactivation due to calcium entry defect 1, is related to combined immunodeficiency due to crac channel dysfunction and myopathy, tubular aggregate, 2. An important gene associated with Immunodeficiency 9 is ORAI1 (ORAI Calcium Release-Activated Calcium Modulator 1), and among its related pathways/superpathways is Antigen activates B Cell Receptor (BCR) leading to generation of second messengers. Affiliated tissues include bone marrow and t cells, and related phenotypes are hypotonia and ectodermal dysplasia
