Genetic and immunophenotypic characteristics of adult T-ALL. Schematic comparison of copy number lesions, genetic mutations, and surface marker expression between early immature and mature/cortical adult T-ALL. Solid circles represent positive leukemia samples. Data were not available for leukemia patients represented by gray filled circles. T-ALL oncogenic subtypes are based on aCGH alterations and microarray expression of T-ALL transcription factor oncogenes.
