There is an estimated 8% decrease in Alzheimer disease incidence without the CLU-MS4A4E risk alleles, according to a study of 3,837 patients with Alzheimer disease and 4,145 controls. Researchers found:
• Results support the CLU-MS4A4E interaction and a dominant effect.
• There is an association between CLU-MS4A4E and APOEɛ negative status.
• Estimated synergy factor for rs11136000-rs670139 is 2.23.
• Odds ratio for rs11136000-rs670139 is 2.45.
• Population attributable fraction (cPAF) for rs11136000-rs670139 is 8.0.
