After the identification of a risk allele for macular degeneration, a polymorphism that causes the substitution of tyrosine for histidine at position 402 in complement factor H (CFH),41,42,43 several additional and independent risk …
… homozygous 5A/5A in MMP3 associated with higher risk acute MI, hemizygous for APOEe4 associated with increased risk for Alzheimers, and possessed a variant in complement factor H linked to increased risk for macular degeneration. …
This grandfather’s family, in conjunction with other families, led to the discovery of the association of changes in the Complement factor H (or CFH) gene with this form of macular degeneration. Not only was the gene identified, …
“It vastly exceeds the risk found previously for the complement-factor-H gene in macular degeneration,” he said. “If a person has risk variants involving TCF4, that individual is anywhere from several to a couple of hundred times more …
