ABSTRACT
ATM gene alterations have been described in various lymphoproliferative malignancies suggesting that ATM contributes to lymphomagenesis. Using multiplex ligation-dependant probe amplification (MLPA), we screened 61 childhood lymphoid malignancies for ATM genomic deletion/duplication. Five samples were found to have a complete deletion or duplication. All the three deletions were found in B-precursor ALL (15%), two were submicroscopic, not detected by standard cytogenetic studies. These observations indicate that as in adult ALL, complete ATM submicroscopic deletion is frequent in childhood B-precursor ALL. As previously hypothesized, these results suggest that ATM may act as a tumor suppressor gene in the pathogenesis of childhood B-precursor ALL.
