Interestingly, there are some indications that a Y402H polymorphism in domain 7 of FH, which significantly increases the risk to age‐related macular degeneration (AMD), could also be associated with AD, although conflicting results on this association have been found in different genetic studies (Zetterberg et al, 2008; Le Fur et al, 2010). Here, FH is linked to age-related macular degeneration.
