Interleukin-8 promoter polymorphism -251A/T is a risk factor for age-related macular degeneration
Open accessAbstract
BACKGROUND/AIMS: To determine whether four expression-related cytokine polymorphisms are associated with age-related macular degeneration (AMD). METHODS: DNA from 478 cases with AMD and 555 normal controls was genotyped for the pro-inflammatory IL1beta -511C/T, IL6 -174C/G, IL8 -251A/T and anti-inflammatory IL10 -1082G/A cytokine polymorphisms using the 5' nuclease TaqMan(R) assay for allelic discrimination. Associations with AMD were analysed using allelic frequencies. RESULTS: The -251A allele of the IL8 promoter gene polymorphism was more prevalent in AMD patients than controls (p = 0.037, OR = 1.21, 95% CI = 1.01 to 1.44). Adjusting for age, sex, body mass index (BMI), current smoking and past smoking status did not alter the AMD association significantly (corrected p value = 0.043, OR = 1.23, 95% CI = 1.0 to 1.50). CONCLUSION: The pro-inflammatory homozygous IL8 -251AA genotype is an important risk factor for AMD. This may have implications for future therapy with biological agents that could target this cytokine.

The IL8 A251T genetic polymorphism is associated with AMD, with the homozygous AA genotype as the at-risk factor.
“The interleukin-8 (IL8) A251T genetic polymorphism located in chromosome 4q13–21 is reported to be associated with AMD, with the homozygous AA genotype (A allele) as the “at risk” factor (Goverdhan et al., 2008).”

SNPs in IL1β C511T, IL6 C174G, and IL10 G1082A showed no significant association with AMD.
“SNPs in other pro-inflammatory chemokines including interleukin-1β (IL1β) C511T, interleukin-6 (IL6) C174G and the anti-inflammatory cytokine IL10 G1082A were analyzed and showed no significant association with AMD (Goverdhan et al., 2008).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
