Human evolutionJAK3 deficiency in humans results in autosomal recessive T-B+ severe combined immunodeficiency disease (SCID), a severe immunodeficiency that can only be cured by bone marrow transplantation. We unraveled the complete organization of the human JAK3 gene, which includes 23 exons. This...
