Table 2 details the patient’s characteristics based on the TSPO rs6971 polymorphism genotype. Out of the 131 GBM patients included in CWRU database, we identified 10 patients with the homozygous wild-type A/A genotype, 67 patients with the heterozygous A/G genotype, and 54 patients with the homozygous variant G/G genotype. There was no difference in the mean age at diagnosis between any of the genotypes; however, there was a significant difference (p = 0.014) in the ratios of males to females between genotypes. The gene discussed is TSPO; the disease is glioblastoma.
