Study population
The general mean age of the B-ALL patients (60% males and 40% females) and ITP subjects (55% males and 45% females) was 6.05 ± 3.77 and 5.05 ± 3.05 years, respectively. The immunophenotyping and cytogenetics data of patients are demonstrated in Table 2. Most of the patients expressed CD3/10/13/19/33/34/79a/ and 117, while the expression of CD2/7/41/ and 61 markers was indicated in fewer patients.
