Among the T-ALL transcripts listed as being over-expressed in Table 2, 7 of 46 are TCR chains (TCRBV5-4, TCRBC1, TCBC1/TCRBV, TCRDC, TCRG2, TCR delta, and TCRGC2) and 4 are members of the CD3 complex (CD3-delta, -epsilon, -gamma, and -zeta), making 11 of 46 (23%) of the T-ALL hits in Table 2 directly related to clonotypic T-cell marker expression. The gene discussed is TRGC2; the disease is acute lymphoblastic leukemia.
