This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Numerous studies suggest the evidence of genes that predispose to development of autoimmunity that may progress to any of a number of diseases with overlapping features such as autoantibody production. This study is designed to evaluated various autoimmunity traits for use as intermediate phenotypes to map genes involved in systemic lupus erythematosus and related autoimmune diseases. A genome scan of several of these trais was recently published and results indicate that, while autoantibody production is a complex trait, there is indeed evidence to support genes specific to cerain autoantibodys and use of these intermediate phenotypes hold promise of providing insight into multiple autoimmune traits.
