studied 10,403 GH-treated patients from 5 of the 8 study countries and found that the standardized incidence risk (SIR) for meningioma was 75.4 (95% CI, 54.9 – 103.6) when compared with year-specific rates from the general population matched for sex, age, and country. The gene discussed is GH1; the disease is meningioma.
