英文摘要
Project Summary
Multiple sclerosis (MS) is a common and severe disorder of the central nervous system
characterized by chronic inflammation, myelin loss, gliosis, varying degrees of axonal and
oligodendrocyte pathology, and progressive neurological dysfunction. MS pathogenesis
includes a complex genetic component. In spite of intensive long-standing efforts by many
research groups, the knowledge of MS genetics remains incomplete. Our overall objective is
to characterize the repertoire of genes that predispose to MS and modulate its presentation.
Their identification is now possible as a result of rapid progress in defining the landscape of
genetic organization and cataloging variation across the human genome.
We are using rigorous clinical criteria to ascertain 2000 MS patients and matched controls of
African-American descent. The African American U.S. population is considered at moderate
risk when compared to white Americans, perhaps reflecting the fact that MS is virtually
absent in native African populations. Based on the hypothesis that genetic heterogeneity is
inherent to MS, and the understanding that patterns of genomic disequilibrium are shaped
by the history of each population, we propose a comprehensive genetic study of African
Americans with MS to identify recombination events and minimal genomic regions harboring
disease genes. Specific Aim 1 will test the hypothesis that there is an HLA-class I effect on
susceptibility independent from class II genes, and test for evidence of association with
combinations of HLA and KIR alleles. Specific Aim 2 describes a large high-resolution
genome-wide association screen, together with a multi-analytical approach to map
unambiguous association signals from sequence and copy number polymorphisms, leading
to testable hypotheses as to which are the specific allelic variants conferring susceptibility.
Specific Aim 3 takes advantage of the unique clinical features of African American MS
patients and proposes a detailed analysis of phenotypic variables and their relationship to
gene variants. This aim directly addresses the question of clinical heterogeneity in MS and
the correlation between different phenotypes and genotypes.
The availability of a unique, large, and well-characterized dataset provides an
unprecedented opportunity to map MS-related genes. In addition, the generated whole-
genome data in African American controls linked to precise assessment of admixture will
serve as an important resource for the scientific community.
