FSH subunit beta (FSHB), encoding the beta subunit of a pituitary glycoprotein that indices gamete production, was associated with endometriosis, uterine fibroids and migraine (Gallagher et al., 2019; Adewuyi et al., 2020), and previous studies also link it to reproductive lifespan, menstrual cycle characteristics, FSH concentrations, and PCOS (McGrath et al., 2021). The gene discussed is FSHB; the disease is endometriosis.
