Association between Polymorphisms in CFH, ARMS2, CFI, and C3 Genes and Response to Anti-VEGF Treatment in Neovascular Age-Related Macular Degeneration. Biomedicines 2022; 10:biomedicines10071658. [PMID: 35884963 PMCID: PMC9312436 DOI: 10.3390/biomedicines10071658] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 05/30/2022] [Accepted: 07/08/2022] [Indexed: 12/16/2022] Open
Abstract
Neovascular age-related macular degeneration (nAMD) is the leading cause of vision loss in the elderly. The gold standard of nAMD treatment is intravitreal injections of vascular endothelial growth factor (VEGF) inhibitors. Genetic factors may influence the response to anti-VEGF therapy and result in a high degree of response variability. The aim of the study was to evaluate the association of the polymorphisms in genes related to the complement system (rs2285714-CFI, rs10490924-ARMS2, rs2230199-C3, rs800292-CFH, and rs6677604-CFH) with nAMD its clinical features and optical coherent tomography (OCT) biomarkers of treatment response to anti-VEGF therapy. Genotyping by allele-specific PCR was performed in 193 AMD patients and 147 age-matched controls. A prospective study of the dynamics of changes in OCT biomarkers during aflibercept treatment included 110 treatment-naive patients. Allele T rs10490924 was associated with the increased risk of nAMD. For both rs800292 and rs6677604, carriage of the A allele was protective and decreased the nAMD risk. Associations of rs2230199 with central retinal thickness (CRT) and intraretinal cysts were revealed. The height of pigment epithelium detachment and the height of neuroretinal detachment were significantly higher in carriers of the minor allele of rs2285714, both at baseline and during treatment. The reduction of CRT was associated with higher CRT at baseline and the presence of the T allele of rs2285714. By the end of one-year follow-up the patients homozygous for the minor allele rs2285714 had significantly higher odds of the presence of anastomoses and loops and active neovascular membrane. Furthermore, minor allele carriers had decreased levels of complement factor I level in aqueous humor but not in the plasma, which may be due to the influence of rs2285714 on tissue-specific splicing. Our results suggest that the severity of AMD macular lesions is associated with rs2285714 and rs2230199 polymorphisms, which could be explained by their high regulatory potential. Patients with the minor allele of rs2285714 respond worse to antiangiogenic therapy.

Abstract
PURPOSE/AIM To explore the relationship between single-nucleotide polymorphisms (SNPs) in complement factor I (CFI), interleukin-8 (IL-8), transferrin (TF), and transferrin receptor 2 (TFR2) and age-related macular degeneration (AMD) in a northeastern Chinese population. METHODS A total of 400 AMD patients (200 wet AMD and 200 dry AMD) and 200 controls were enrolled in this study, and genetic polymorphisms in the above genes were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The χ2 test was used to compare differences in allele frequencies in each group, and the associations of genotype frequencies with AMD were determined by multivariate logistic regression analysis. RESULTS Our research shows that CFI rs141853578, IL-8 rs2227543, TF rs8177178 and TFR2 rs2075674 are associated with the incidence of AMD. In wet AMD, allele T of CFI rs141853578, IL-8 rs2227543 and TFR2 rs2075674 may be a risk factor. Allele A of TF rs8177178 may increase the risk of dry AMD. CONCLUSIONS CFI rs141853578, IL-8 rs2227543, TF rs8177178 and TFR2 rs2075674 genetic polymorphisms are associated with the occurrence of AMD in a northeastern Chinese population, especially wet AMD.

Complement family member CFI polymorphisms and AMD susceptibility from a comprehensive analysis. Biosci Rep 2021; 40:222471.

Abstract
The complement factor I (CFI) gene polymorphisms have been reported to age-related macular degenerative (AMD) risk, nevertheless, above association is not consistent. We investigated a meta-analysis to evaluate the conclusions between CFI polymorphisms (rs10033900 and rs2285714) and AMD risk. An identification was covered with the PubMed and other databases through February 8, 2020. Odds ratios (OR) and 95% confidence intervals (CI) were used to assess the strength of associations. After a comprehensive search, 11 different articles (12 case–control studies for total AMD and 11 case–control studies about neovascular disease/geographic atrophy in AMD) were retrieved. Individuals carrying C-allele or CC genotype of rs10033900 polymorphism may have a decreased risk to be AMD disease. For example, there has a significantly decreased relationship between rs10033900 polymorphism and AMD both in the whole group, Caucasian population and population-based source of control. Moreover, a similar trend in subgroup of genotype method group by MALDI-TOF MS was detected. To classify the type of AMD in further, decreased association was also observed in both neovascular disease and geographic atrophy AMD. No association was found about rs2285714 polymorphism. Our present groundbreaking study suggests that the CFI rs10033900 polymorphism is potentially associated with the risk of AMD development.
