GPX4 and myeloid sarcoma: As shown in Table 4, the C/C genotype and the C allele of the c.660 T > C—GPX4 SNP were linked with a decreased frequency of MS occurrence in the male group (Crude OR 0.414; 0.190–0.902; 95% CI; p < 0.05; Crude OR 0.537; 95% CI; p < 0.05, respectively), while this dependence was not observed in females.
