 Immunogenetic Determinants of Disease Risk in Neurological Disease
 Biography Overview ? DESCRIPTION (provided by applicant): This project, submitted as a multi-center U19 application on behalf of the Immunogenetics of Neurological Diseases working GrOup (INDIGO), has as its primary goal to identify and characterize the repertoire of HLA and KIR genes and alleles that predispose to neurological diseases. WE focus the effort on multiple sclerosis, neuromyelitis optica, myasthenia gravis, Parkinson's disease, and schizophrenia - all diseases with established association signals in the Major Histocompatibility Complex (MHC). To achieve our goals, we have assembled a multi-disciplinary international team that brings together complementary expertise (immuno- and neuro-genetics, clinical, and computational) and a remarkable track record of productivity to carry out a study of broad scope and depth. Through this collaboration, we will leverage rich and informative datasets exceeding 15,000 study participants (cases) and connect genetics with CNS disease utilizing advanced molecular and bio-informatics tools. The study design includes 2 independent, yet interactive Projects supported by a common administrative and data/sample management infrastructure. Project 1 proposes a comprehensive sequence variation screening in nine HLA loci and association analysis with disease risk. Project 2 will assess the distribution of KIR-associated variants, KIR copy number, and KIR promoter polymorphisms in the same diseases. Both projects will take advantage of the ancestral diversity of the datasets to advance the fine mappings of the discovered associations. Naturally, we will also pursue the analysis of HLA-KIR interactions vis-?-vis disease susceptibility. Genetic pleiotropy and the identification of common immunogenetics across diseases are additional important elements of this initiative. The overarching goal of this project is to achieve a productive integration of molecular and clinical datasets to elucidate the genetic pathways that drive risk to CNS injury and neurodegeneration. The isolation of definite HLA- KIR associations with the risk of neuroinflammation and neurodegeneration could be transformative by revealing fundamental insights about primary disease mechanisms.
