Summary
Multiple sclerosis (MS) is a disease that affects around 10,000 Australians. It is a disease of young adults with women being affected more often than men. While there are therapeutics available to treat it, these are very expensive ($10-12,000 per annum) and are effective in only a proportion of affected individuals. MS is governed by a complex interplay of environmental and genetic susceptibility factors, neither alone sufficient to cause disease, however, the study of these factors has been c ....Multiple sclerosis (MS) is a disease that affects around 10,000 Australians. It is a disease of young adults with women being affected more often than men. While there are therapeutics available to treat it, these are very expensive ($10-12,000 per annum) and are effective in only a proportion of affected individuals. MS is governed by a complex interplay of environmental and genetic susceptibility factors, neither alone sufficient to cause disease, however, the study of these factors has been confounded by the complex nature of the disease. We and other researchers have identified the human leukocyte antigen (HLA) complex on chromosome 6 as harbouring susceptibility genes for MS. Our recent work has localised these genes in two distinct regions of the HLA complex. In this project we plan to localise these genes more precisely to permit their identification. By identifying these genes we hope to develop an understanding of their function in a healthy person and in a person with MS. Understanding what goes wrong during disease is a critical first step along the track to the design of novel therapeutics. A successful therapeutic agent would be designed to interfere with disease processes and treat the disease more effectively.Read moreRead less
Major Histocompatibility Complex (MHC) Genetics Of Ankylosing Spondylitis

Summary
Ankylosing spondylitis (AS) is the prototypic condition of a group of types of inflammatory arthritis called 'seronegative spondyloarthropathies'. These conditions are the most common form of inflammatory arthritis in white populations and occur worldwide. One third of the risk of developing AS is determined by genes within a region called the 'major histocompatibility complex' (MHC), in addition to the gene HLA-B27, the main gene causing AS. We aim to identify the remaining MHC genes.
The Immunogenetics Of Ankylosing Spondylitis: A Genetic And Functional Investigation Of IL23R And Related Genes

Summary
Ankylosing spondylitis (AS) is a common inflammatory arthritis which causes primarily back pain and stiffness, and affects 1-250 individuals. Our group identified association between tagging genetic markers in the gene IL23R and AS, and our preliminary data suggests some related genes are involved as well. This study aims to identify the key genetic variants involved and determine the mechanism by which they cause AS.
