Abstract

Age-related macular degeneration (AMD) is the most common cause of irreversible visual impairment in the developed world. The two forms of advanced AMD, geographic atrophy (GA) and choroidal neovascularization (wet AMD), represent two types of degenerative processes in the macula that lead to loss of central vision. Soft confluent drusen, characterized by deposits in macula without visual loss are considered a precursor of advanced AMD. A single nucleotide polymorphism, rs11200638, in the promoter of HTRA1 has been shown to increases the risk for wet AMD. However, its impact on soft confluent drusen and GA or the relationship between them is unclear. To better understand the role the HTRA1 polymorphism plays in AMD subtypes, we genotyped an expanded Utah population with 658 patients having advanced AMD or soft confluent drusen and 294 normal controls and found that the rs11200638 was significantly associated with GA. This association remains significant conditional on LOC387715 rs10490924. In addition, rs11200638 was significantly associated with soft confluent drusen, which are strongly immunolabeled with HTRA1 antibody in an AMD eye with GA similar to wet AMD. Two-locus analyses were performed for CFH Y402H variant at 1q31 and the HTRA1 polymorphism. Together CFH and HTRA1 risk variants increase the odds of having AMD by more than 40 times. These findings expand the role of HTRA1 in AMD. Understanding the underlying molecular mechanism will provide an important insight in pathogenesis of AMD.

  • rs11200638 in the HtrA1 promoter is the most well-documented, statistically significant AMD-associated SNP, with odds ratios of 1.60-2.61 in heterozygous and 6.56-10.0 in homozygous individuals (Caucasians, Chinese, Japanese).

    “Several studies have shown that rs11200638 in the promoter region is the most well-documented, statistically significant AMD-associated SNP with a high OR of 1.60–2.61 and 6.56–10.0 in heterozygous and homozygous individuals (Caucasians, Chinese and Japanese), respectively (Cameron et al., 2007; Deangelis et al., 2008; Dewan et al., 2006; Mori et al., 2007; Tam et al., 2008; Yang et al., 2006).”

  • Elevated expression of HtrA1 mRNA and/or protein in drusen and CNV components has been reported in AMD patients carrying the AA risk genotype.

    “Elevated expression of HtrA1 mRNA and/or protein in the drusen and CNV components in AMD patients carrying the AA risk genotype has been reported in several studies (Cameron et al., 2007; Chan et al., 2007; Tuo et al., 2008; Yang et al., 2006) (Fig. 6).”

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.
