Genetic mediators of functional magnetic resonance imaging (fMRI) activity among childhood acute lymphoblastic leukemia survivors. Group-level fMRI contrasts during the N-Back and attention network tasks based on genetic variants. Individuals with heterozygous and minor homozygous alleles (HeteroMinor) were compared with major homozygous alleles (Major) using multivariable analyses adjusted for age at evaluation and sex. Differences in brain activity were statistically significant for family wise error–corrected P values less than .05. Blood oxygen level–dependent (BOLD) activation differences were observed in A) the left angular gyrus; B) right supramarginal gyrus; C) right orbital inferior frontal gyrus and supramarginal gyrus; and D) left caudate nucleus, basal ganglia, and inferior frontal gyrus.
