Answer

Although a few cases are associated with inherited genetic syndromes (eg, Down syndrome) or congenital immunodeficiencies (eg, Wiskott-Aldrich syndrome, ataxia-telangiectasia), the cause remains largely unknown. [4] Environmental risk factors such as exposure to ionizing radiation and electromagnetic fields and parental use of alcohol and tobacco have not been shown to cause pediatric acute lymphoblastic leukemia. In addition, no direct link has been established between viral exposure and the development of childhood leukemia.
