Abstract

Advanced age-related macular degeneration (AMD) is the leading cause of late onset blindness. We present results of a genome-wide association study of 979 advanced AMD cases and 1,709 controls using the Affymetrix 6.0 platform with replication in seven additional cohorts (totaling 5,789 unrelated cases and 4,234 unrelated controls). We also present a comprehensive analysis of copy-number variations and polymorphisms for AMD. Our discovery data implicated the association between AMD and a variant in the hepatic lipase gene ( LIPC ) in the high-density lipoprotein cholesterol (HDL) pathway (discovery P = 4.53e-05 for rs493258). Our LIPC association was strongest for a functional promoter variant, rs10468017, ( P = 1.34e-08), that influences LIPC expression and serum HDL levels with a protective effect of the minor T allele (HDL increasing) for advanced wet and dry AMD. The association we found with LIPC was corroborated by the Michigan/Penn/Mayo genome-wide association study; the locus near the tissue inhibitor of metalloproteinase 3 was corroborated by our replication cohort for rs9621532 with P = 3.71e-09. We observed weaker associations with other HDL loci ( ABCA1 , P = 9.73e-04; cholesterylester transfer protein, P = 1.41e-03; FADS1-3 , P = 2.69e-02). Based on a lack of consistent association between HDL increasing alleles and AMD risk, the LIPC association may not be the result of an effect on HDL levels, but it could represent a pleiotropic effect of the same functional component. Results implicate different biologic pathways than previously reported and provide new avenues for prevention and treatment of AMD.

TL;DR

This GWAS of advanced AMD (979 cases/1,709 controls in discovery; 5,789 cases/4,234 controls in replication) identified a replicated association at *LIPC* rs10468017 (P = 1.34 × 10⁻⁸), with the minor T allele protective (OR = 0.82). Other HDL loci showed weaker or inconsistent associations, suggesting the *LIPC* effect may not be mediated by HDL levels.

Key findings

  • *LIPC* rs493258 was associated in discovery (P = 4.53 × 10⁻⁵) and reached P = 1.61 × 10⁻⁸ after replication; the functional promoter variant rs10468017 gave P = 1.34 × 10⁻⁸, OR = 0.82 (95% CI 0.77–0.88), with minor T allele frequency 25.8% in cases vs 30.0% in controls.
  • rs9621532 near *TIMP3*/*SYN3* showed a protective effect for the minor C allele (OR = 0.62, 95% CI 0.53–0.73, P = 3.71 × 10⁻⁹) in combined analysis.
  • Other HDL loci were weaker and directionally inconsistent: *ABCA1* rs1883025 P = 9.73 × 10⁻⁴, *CETP* rs3764261 P = 1.41 × 10⁻³, *FADS1-3* rs174547 P = 2.69 × 10⁻²; no consistent trend between HDL-raising alleles and AMD risk was observed.
  • CNV analyses found no common CNPs with P < 0.001 except the previously reported *CFHR1* deletion (P = 1 × 10⁻¹⁹), explained by known *CFH* variants, and no genome-wide enrichment of rare CNVs in cases vs controls.

Methods

  • Discovery GWAS used 979 unrelated advanced AMD cases and 1,709 controls genotyped on Affymetrix 6.0; replication included seven additional cohorts totaling 5,789 unrelated cases and 4,234 unrelated controls.
  • Association was assessed by logistic regression in PLINK, with meta-analysis using weighted Z scores; final genomic control λ was 1.036 for 632,932 SNPs after including seven principal components.
  • CNV analysis used Birdsuite/CANARY/Birdseye for 554 common CNPs and rare CNVs >100 kb; LIPC expression was examined by immunoprecipitation, quantitative RT-PCR, and immunohistochemistry in bovine, mouse, and human retinal samples.

Limitations

  • Stated: modest heterogeneity was observed for rs10468017 across replication samples (Breslow–Day P = 0.022); the UT sample lacked association and FR-CRET had higher-than-expected association, though excluding both strengthened the result (P = 6.45 × 10⁻⁹).
  • Stated: the scan did not have sufficient statistical power to conclusively highlight weak or moderate subtype-specific SNP associations between advanced dry and wet AMD.
  • Evident from the text: additional discovery controls were unscreened for AMD status, and the Tufts/MGH replication set included 379 unexamined controls, which could affect phenotype classification; the case-control design also cannot establish causality.

    The authors' 1997 study of the TIMP3 locus and AMD in 38 AMD families did not find evidence of association or linkage between AMD and TIMP3.

    “Our study of the *TIMP3* locus and AMD in 1997, inspired by the association of this gene to Sorsby fundus dystrophy that has similar phenotypic features to advanced AMD, did not find evidence of association or linkage between AMD and *TIMP3* among 38 AMD families.”

    Interpretationreasoning

    The association between advanced AMD and LIPC may not represent phenotypic correlation to or a causal effect of serum HDL but could indicate a shared underlying biologic mechanism involving the cholesterol pathway.

    • Rests on an assumption: If the LIPC-AMD association were driven by HDL levels, all SNPs associated with HDL would show some association with AMD and in a consistent direction.

    Heterogeneity in rs10468017 association could be attributed to yet to be discovered genotype or phenotype correlations and ascertainment differences between samples.

  • The paper relies on this without support.

    No large sample genome-wide association study had previously been undertaken to explain the remaining heritability of AMD and to identify other susceptibility loci.

    “To date, however, no large sample genome-wide association study (GWAS) has been undertaken to attempt to explain the remaining heritability of AMD and to identify other susceptibility loci.”
  • The paper relies on this without support.

    The T allele of the LIPC SNP increases HDL levels.

    “The T allele of the *LIPC* SNP has been shown to increase HDL levels”
  • The paper relies on this without support.

    If the LIPC-AMD association were driven by HDL levels, all SNPs associated with HDL would show some association with AMD and in a consistent direction.

    “If the association between *LIPC* and AMD was driven by this phenotypic correlation, then all SNPs associated with HDL would likely show some level of association with AMD. Additionally, the direction of the effects would be consistent.”
  • The paper relies on this without support.

    The MPM scan and the authors' scan are comparable enough that exchanging SNPs enables valid primary replication.

    “SNPs with *P* < 10−3 from our GWAS discovery sample (*n* = 720 SNPs excluding previously associated regions) were exchanged with the MPM study group, which enabled us to use the two scans as primary replication efforts, and enhanced the power of each study.”

Each contradiction between two passages listed here was confirmed by an independent check.

  • Odds ratio falls outside its reported confidence interval

    Minor

    For rs11755724, the reported meta-analysis odds ratio is 0.87, but its stated 95% confidence interval is 0.88-0.92. A confidence interval for that odds ratio should contain the estimate.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

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.
