Gene Segment Usage of Functional TCRβ Rearrangements in T-Cell Clones of AILD

Case	Vβ segment	Jβ segment
1	2S1	1.6
2	13S1	1.5
3	13S1	1.5
5	13S1	1.1
10	15S1	2.7
11*	17S1/18S1	2.6/1.1
14	9S1	2.2
15	5S1	1.1
16	13S1	1.2
18	2S1	1.6

*Two in-frame gene rearrangements were amplified in case 11 (Vβ17S1Jβ2.6/Vβ18S1Jβ1.1).
