As shown in Table 7, CCND1 rs9344 was related with grade 3–4 acute radiation-induced oral mucositis in recessive model among patients < 51 years old, and it was also related with grade 3–4 acute radiation-induced myelosuppression in additive and recessive models among patients with BMI < 22.8. Here, CCND1 is linked to myelosuppression.
