TCL1A（T cell leukemia/lymphoma 1A），癌症关联基因，基因ID：8115，TCL1基因在人类中的过度表达与成熟T细胞白血病的发生有关，其中染色体重排使TCL1基因接近T细胞抗原受体（TCR）-α（MIM 186880）或TCRβ（MIM 186930）调节元件（由VygILIO等，1998 [PubMed 9520462 ]概括）。在正常T细胞中，TCL1在CD4-/CD8-细胞中表达，但在分化后期细胞中不表达TCL1作为细胞存活激酶AKT（MIM 164730）的辅活化子（Laine等人，2000年[出版编号10983986]）。[由OMIM提供，2010年7月]Overexpression of the TCL1 gene in humans has been implicated in the development of mature T cell leukemia， in which chromosomal rearrangements bring the TCL1 gene in close proximity to the T-cell antigen receptor (TCR)-alpha (MIM 186880) or TCR-beta (MIM 186930) regulatory elements (summarized by Virgilio et al.， 1998 [PubMed 9520462]). In normal T cells TCL1 is expressed in CD4-/CD8- cells， but not in cells at later stages of differentiation. TCL1 functions as a coactivator of the cell survival kinase AKT (MIM 164730) (Laine et al.， 2000 [PubMed 10983986]).[supplied by OMIM， Jul 2010]。
