Gene: JAK1
IUIS: Inheritance - AD GOF (Causes JAK1 GOF. Hyperactive JAK1. Associated with HSM, eosinophilia, eosinophilic enteritis, thyroid disease, poor growth, viral infections), AR LOF (causes JAK1 deficiency. Affects N + L cells. Reduced JAK1 activation to cytokines, Reduced IFN-gamma production. Associated with susceptibility to mycobacteria and viruses, urothelial carcinoma).Created: 15 Apr 2020, 12:09 p.m. | Last Modified: 15 Apr 2020, 12:09 p.m.
