When the Human Genome Project successfully sequenced the last of the more than 3 billion nucleotides that make up the human genome in 2003, it was hailed as the operating manual for the approximately 20,000 genes that determine all of the shared and unique characteristics that determine a human being. Little did we know that it was just the beginning.
Today, we know that roughly 90% of the genetic variations within the human genome that are responsible for unique traits and, possibly, enhanced disease risk are not found in those ~ 20,000 genes, but are instead in regions of non-coding DNA; regions once coined “junk DNA”. We also know that many of these non-coding genetic variations are located in regulatory regions that control gene expression. The unique characteristics of an individual, as well as the risk for developing complex heritable diseases, are the result of thousands of inherited non-coding genetic variations that collectively modify gene expression.
I have dedicated my research career to identifying which non-coding genetic variations are associated with the debilitating autoimmune disease, systemic lupus erythematosus (lupus), and how those genetic variations function to disrupt the immune system, leading to inflammation, organ failure, and, in some cases, premature death. By improving our understanding of the complex regulatory mechanisms embedded within the human genome, we hope to advance early detection strategies and the development of more effective treatments for lupus.
My primary research focus is to decipher the complex genetic landscape of lupus and other autoimmune diseases. Like other autoimmune diseases, lupus is characterized by a production of autoantibodies that attack a wide variety of tissues and organs resulting in systemic inflammation and organ failure.
Our work has contributed significantly over the last decade to establish a strong genetic basis for lupus, and to provide important information about how genetic variations influence immune cell function to drive lupus development and progression. We use state-of-the-art high throughput sequencing technologies coupled with bioinformatics and functional analyses to systematically evaluate how genetic variations associated with lupus alter the genetic landscape and subsequent gene expression. Our overall objective is to develop a comprehensive view of the genetic landscape of lupus that can then be used to develop new or improved predictive and monitoring tools for patients with lupus.
