From Wikipedia, the free encyclopedia

ZAP70 deficiency (zeta-chain-associated protein 70 kD deficiency) is a rare, autosomal recessive form of severe combined immunodeficiency (SCID).[1]



It is characterized by a lack of CD8+ T cells and the presence of circulating CD4+ T cells which are unresponsive to T-cell receptor (TCR)-mediated stimuli.[2]


ZAP70 deficiency has an autosomal recessive pattern of inheritance.

No cure currently exists; however, gene therapy has been proposed.[3][4]
