a. Down syndrome
b. Wilms tumor
c. Retinoblastoma
d. Neuroblastoma - Answer ANS: A
Trisomy 21 (Down syndrome) is the most common genetic defect linked to the development of
acute leukemia. Children with
Down syndrome have a 10- to 20-fold increased risk of developing acute lymphoblastic and
myelogenous leukemia and a higher

tissue, bone, cartilage, muscle,
blood, blood vessels, gonads, kidney, and the lymphatic system. The epithelium, embryologic
ectodermal layer, and the viscera are
not common sites from which cancers originate.
