Meta-analysis of the rs243865 MMP-2 polymorphism and age-related macular degeneration risk.

ABSTRACT: PURPOSE:Several researchers have suggested that the rs243865 (16q13-q21) polymorphism in the promoter region of the metalloproteinase-2 (MMP-2) gene could be associated with an increased risk of developing age-related macular degeneration (AMD). However, previous results remain inconclusive. To clarify this controversy, we conducted a meta-analysis of the relationship between rs243865 of MMP-2 and AMD. METHODS:We included 6 independent case-control studies involving 1,682 AMD patients and 2,295 healthy subjects. The association between the rs243865 polymorphism and AMD was examined by the overall odds ratio (OR) with a 95% confidence interval (CI). We used a recessive genetic model analysis, sensitivity analysis, and assessment of bias in our meta-analysis. RESULTS:Our results showed that there was no significant association between the variant T allele (p-value = 0.10, OR [95%CI] = 0.95 [0.82-1.10]) or the CT+TT genotype (p-value = 0.16, OR [95%CI] = 0.92 [0.76-1.12]) of rs243865 MMP-2 polymorphism and the presence of AMD. CONCLUSIONS:The rs243865 MMP-2 polymorphism was not associated with an increased risk of developing AMD. The MMP-2 (-1306 C>T) promoter variant is unlikely to have a major role in AMD risk susceptibility.

Project description:PurposeWe previously identified a genetic copy number polymorphism (CNP147) that was statistically associated with age-related macular degeneration (AMD) and that resides downstream of the complement factor H (CFH) gene. Factor H protein is polymorphic at amino acid 402, in which the resulting histidine containing moiety has been established to impart significant risk of AMD. We present a method to precisely determine the exact copy number of CNP147 and examine in more detail the association with AMD.DesignCase-control study.ParticipantsA total of 421 Age-Related Eye Disease Study (AREDS) subjects, of whom approximately 35% were diagnosed with neovascular disease, 19% were diagnosed with geographic atrophy, 16% were diagnosed with both, 30% were diagnosed with large drusen, and 215 were controls.MethodsBy using copy number assays available from Applied Biosystems Inc. (Carlsbad, CA), we examined 4 loci spanning CNP147 and neighboring CNP148 in an AREDS matched case-control sample set. We analyzed these data by copy number while controlling for 2 high-risk CFH variants, rs1061170 (Y402H) and rs1410996. We phased the high-risk CFH variants with CNP147 and analyzed haplotype frequencies in cases and controls. To further validate copy numbers, 6 Utah Centre D'etude du Polymorphism Humaine (CEPH) families were typed for CNP147, and the segregation was assessed.Main outcome measuresIncreased or decreased risk of AMD from genetic loci.ResultsHaving fewer than 2 copies of CNP147 was associated with an estimated 43% reduction in odds of having AMD in this sample set (adjusted odds ratio [OR] = 0.57, P=0.006). CNP148 variation is rare in Caucasians and was not statistically significant. Common haplotypes reveal that the risk alleles for rs1061170 and rs1410996 most frequently segregate with higher copy numbers for CNP147, but not exclusively, and that 1 haplotype that carried a deletion of CNP147 was highly protective (OR = 0.25 P=1.3×10(-13)) when compared with the reference.ConclusionsIn this matched subset of AREDS subjects, after adjusting for 2 known risk variants in CFH, CNP147 deletion statistically associates with diminished risk for AMD.Financial disclosure(s)The author(s) have no proprietary or commercial interest in any materials discussed in this article.
