ESR1 and exstrophy-epispadias complex: The basal-like subgroup had a much higher number of tumors with higher pathological grade (p < 0.0001), and TNM stage (p = 0.01); in the luminal-like subgroup, progesterone (PGR) and estrogen receptor (ESR1) genes were not downregulated as in the EEC basal-like subgroup.
