Journal ArticleDOI
A common haplotype in the complement regulatory gene factor H (HF1/CFH) predisposes individuals to age-related macular degeneration

TL;DR: It is shown that factor H (HF1), the major inhibitor of the alternative complement pathway, accumulates within drusen and is synthesized by the retinal pigmented epithelium, implicating HF1 function in the pathogenetic mechanisms underlying AMD.
Journal ArticleDOI
Variation in factor B (BF) and complement component 2 (C2) genes is associated with age-related macular degeneration
Bert Gold,Joanna E. Merriam,Jana Zernant,Lisa S. Hancox,Andrew J Taiber,Karen M. Gehrs,Kevin Cramer,Julia Neel,Julie Bergeron,Gaetano R. Barile,R. Theodore Smith,Gregory S. Hageman,Michael Dean,Rando Allikmets +13 more
TL;DR: Combined analysis of the C2 and BF haplotypes and CFH variants shows that variation in the two loci can predict the clinical outcome in 74% of the affected individuals and 56% ofThe controls, expanding and refine the understanding of the genetic risk for AMD.

TL;DR: The results support the hypothesis that rare coding variants can pinpoint causal genes within known genetic loci and illustrate that applying the approach systematically to detect new loci requires extremely large sample sizes.
