Although AHR was found in many cancers (24% of all tumors) and specific tumor types (for example, 55% of cases of malignant lymphoma) (Extended Data Fig. 9c), it contributed to a minority of UPD events, most of which were progressive (31% P-UPD versus 1% AHR-UPD by total width) (Fig. 4d). This evidence concerns the gene AHR and cancer.
