IKBKG and age-related macular degeneration: Moreover, serum IKBKG concentrations were considerably lower in exudative AMD patients with the GG genotype of IKBKG rs2472394 than in controls (median (IQR): 0.434 (0.199) vs. 0.603 (0.335), p = 0.012), leading to the hypothesis that the IKBKG rs2472394 variant might play a role in protein concentration differences and exudative AMD development, but additional investigations are needed to confirm the mentioned findings.
