ITK (Tyrosine-protein kinase ITK/TSK) variants and mutations

ITK (also known as Tyrosine-protein kinase ITK/TSK) is a human protein-coding gene encoding a tyrosine-protein kinase ITK/TSK protein. A Tec-family kinase that relays T-cell receptor signals needed for T-cell development and activation. Deficiency can cause combined immunodeficiency. This analysis covers 801 ITK variants and mutations. Of these, 92% have computational variant effect predictions. Disease context includes lymphoproliferative syndrome 1, autosomal recessive lymphoproliferative disease, and renal cell carcinoma. Example ITK variants include N2S, N2N, and N3D.
