PBX1 and androgen insensitivity syndrome: OS was significantly better in E2A-PBX1 fusion transcripts (-) group than that in E2A-PBX1 fusion transcripts (+) group in stage IA patients with AIS (p = 0.0363; hazard ration 0.04104; 95% CI, 0.002065 ~ 0.8157) (Figure 2E) and female stage IA patients with AIS (p = 0.0174; hazard ration 0.02174; 95% CI, 0.0009266 ~ 0.5100) (Figure 2F).
