FNTA and inflammatory bowel disease: Farnesyltransferase FNTA (farnesyltransferase, CAAX box, alpha) was also among the results, along with BLK tyrosine kinase (BLK proto-oncogene, Src family tyrosine kinase), which may phosphorylate FCGR2A, -B, and -C, and which is correlated with IBD genes ZAP70 (zeta chain of T-cell receptor-associated protein kinase 70; r = 0.81, p = 1.4 × 10−121) and ITGAL (integrin subunit alpha L; r = 0.80, p = 4.1 × 10−119).
