GENETIC SUSCEPTIBILITY. “Early landmark studies have shown that mice carrying mutations in individual genes related to the circadian clock (mutation of period 2 (Per2m/m); heterozygous ablation of aryl hydrocarbon receptor nuclear translocator–like protein 1 (Arntl) (Bmal1+/–); and double-null cryptochrome 1 (Cry1) and Cry2 (Cry1/2–/–)) are more susceptible to lymphoma, and when irradiated, these mutant mice have increased rates of lymphoma and hepatocellular carcinoma.”
