Similarly, ERCC2 rs1799793 A/A genotype showed association with anemia (OR = 27.00, CI = 1.68–434.44, p-value = 0.020), ERCC2 rs238406 A/A genotype was associated with leukopenia (OR = 5.5, CI = 1.26–24.10, p-value = 0.024) and ERCC2 rs13181 T/G genotype was linked with alopecia (OR = 10.86, CI = 1.16–101.35, p-value = 0.036), indicating that defects in the metabolism and/or the response to cisplatin could lead to the specific severe ADRs (Table 3). This evidence concerns the gene ERCC2 and anemia (phenotype).
