Wilcoxon tests with Benjamini Hochberg adjustments showed that boxers had higher plasma concentrations of GFAP (δ = 0.810 [CI = 0.133, 0.971, p < .001), p-tau181 (δ = 0.540 [CI=−0.043, 0.849], p = .049) and p-tau217 (δ = 0.508 [CI=−0.055, 0.826], p = .046)) than patients with SCD. The gene discussed is GFAP; the disease is Schnyder corneal dystrophy.
