GH peak to GST significantly correlated with serum IGF-1 SDS levels in the entire cohort (ρ = 0.68, P < .001) even after excluding female patients who were receiving HRT, in OS-GHD (ρ = 0.81, P < .001), and in OM-GHD (ρ = 0.50, P = .002) groups. The gene discussed is IGF1; the disease is ocular melanoma.
