Background: Dysregulation of WNT signaling has been reported in many malignancies.Objective: This study was conducted to investigate the expression pattern of 14members of the WNT gene family in different immunophenotypic subtypes of ALL.Methods: Semi-quantitative RT-PCR was performed on samples from 71 ALL patientsand 36 age-matched healthy individuals. The ALL patients were categorized into BALL(76%), T-ALL (22.6%) and mixed lineage (1.4%) and the B-ALL cases were furtherclassified into pro-B, pre-BI, pre-BII and immature/mature-B based on immunophenotypicresults. Results: Among the WNT genes, WNT-7B (p=0.026), WNT-9A(p=0.020) and WNT-16B (p=0.023) were significantly over-expressed, whereas WNT-2B (p=0.033), WNT-5A (p=0.016), WNT-7A (p
