PNP and Schnyder corneal dystrophy: The 20‐week treatment with 8‐AG reduced hypoxanthine (p = 0.036, Figure 3C) and guanine (p = 0.047, Figure 3I) and increased the inosine/hypoxanthine ratio (p = 0.048, Figure 3F) and guanosine/guanine ratio (p = 0.001, Figure 3J), suggesting an efficient inhibition of PNP by 8‐AG in SCD mice (see Figure S1C,G,I,J).
