Immunodeficiency 9

Disease ID:1257
Name:Immunodeficiency 9
Associated with:1 target
1 immuno-relevant target
Immune dysfunction with T-cell inactivation due to calcium entry defect 1
IMD9 is a severe, autosomal recessive disorder caused by loss-of-function mutations in the ORAI1 gene which result in deficient CRAC channel function, and defective T-cell activation. The disease is characterised by neonatal onset of recurrent infections, congenital myopathy and ectodermal dysplasia.
