A Comprehensive Genetic Association Study of Alzheimer Disease in African Americans
AssociationN=1,009Logue MW et al.(2011)· Archives of Neurology

This comprehensive genome-wide association study examined genetic variants contributing to late-onset Alzheimer's disease (AD) in 513 African American cases and 496 controls, plus replication in 5 white cohorts. The APOE ε4 allele showed strong association (P=9.69×10⁻²³), and after adjusting for APOE, rs6859 in PVRL2 remained significantly associated (P=0.0087). The study found associations with variants in CLU, PICALM, BIN1, EPHA1, MS4A, ABCA7, and CD33, though effect directions sometimes differed from white populations. Novel associations with suggestive evidence were identified in PROX1, CNTNAP2, STK24, and other genes, though not replicated in whites.

About APOC1

This gene encodes a member of the apolipoprotein C1 family. This gene is expressed primarily in the liver, and it is activated when monocytes differentiate into macrophages. The encoded protein plays a central role in high density lipoprotein (HDL) and very low density lipoprotein (VLDL) metabolism. This protein has also been shown to inhibit cholesteryl ester transfer protein in plasma. A pseudogene of this gene is located 4 kb downstream in the same orientation, on the same chromosome. This gene is mapped to chromosome 19, where it resides within a apolipoprotein gene cluster. Alternative splicing and the use of alternative promoters results in multiple transcript variants.
