NCAM1 and ataxia telangiectasia: There was no evidence of association between the kinetics of T, NK, and B cells and the occurrence of malignancy in AT patients considering death without malignancy as competing risk event (CD3+ T cells p = 0.376; CD3+CD8+ T cells p = 0.541; CD3+CD4+ T cells p = 0.237; CD3-CD56+ NK cells p = 0.776; CD3+CD56+ NKT-like cells p = 0.321; CD19+ B cells p = 0.725; Figures 1C–H).
