Genes determine your height, hair color and even, in some cases, whether or not you will get certain diseases. Much of what scientists know about human disease today has been learned from the study of genetics, and in my lab, we focus on how genes can trigger the onset of disease. In particular, we study the role that genes play in cancer and autoimmune disease.

Today, approximately 5 percent of colon cancers are known to have genetic causes. Our lab is now looking for other genetic factors that could trigger the disease. By pinpointing a genetic basis for certain colon cancers, it may be possible to determine those at high risk of developing them. Such insight could be crucial into extending the lives of patients, as colon cancer is often curable when treated early.

We also study the genetic factors that lead to the development of autoimmune diseases. We focus our work on two such conditions—lupus and sarcoidosis.

In lupus, the body’s immune system attacks its own cells and tissues. Our lab is working to identify the genes responsible for the initial launching of these attacks. By discovering the point where the immune system turns on itself, scientists can develop ways to stop the disease’s progression before damage occurs. Finding new treatments for lupus represents a major unmet medical need, as it has been 50 years since the FDA approved a new treatment for this debilitating, sometimes fatal disease that affects up to 10 million people worldwide.

Sarcoidosis occurs when small nodules form in and around organs, leading to arthritis-like swelling and inflammation. This poorly understood condition is more common and severe in African Americans than in Caucasians. By studying family members with the disease, we hope to find the genes that cause this condition, information that ultimately could lead to more effective methods of treatment.

My laboratory is focused on the identification of genes predisposing to complex diseases, particularly colon cancer and inflammatory disorders like systemic lupus erythematosus (SLE) and sarcoidosis. We are also involved in the development of new statistical and computational tools to aid in the discovery of these genes.

Colorectal cancer is the second leading cause of cancer mortality in adult Americans with each American carrying a 6% lifetime risk of developing the disease. While early stage cancers can be highly curable, late stage colon cancers remain incurable. Both somatic and germline mutations have been associated with the development of colon cancer and its precursor adenomatous colon polyps (ACPs). However, familial colon cancers with known cause: Familial Adenomatous Polyposis (FAP) and Hereditary Nonpolyposis Colorectal Cancer (HNPCC) account for <1% and ~5% of all colon cancer cases annually, respectively. Our studies, in collaboration with our colleagues at Case Western Reserve University, are aimed at identifying additional alleles predisposing to colon neoplasia vital to describing individuals at high risk for developing colon cancer, and for whom colon cancer screening and early detection can have potentially life-saving benefits.

SLE is a systemic autoimmune disease most frequently and severely affecting women and has diverse clinical manifestations involving the joints, kidneys, brain, and several other organ systems. OMRF and our studies have played a major role in a longstanding effort devoted to identifying genes involved in SLE. The focus of my most recent work in this area is the identification of genes involved in the targets of the earliest autoimmune response. Identification of these genes would give us insight into the biological mechanisms underlying SLE and, potentially, other autoimmune disorders and therefore the ability to intervene in disease progression before or at the earliest stages of clinical presentation.

Sarcoidosis, a systemic granulomatous disease, has been associated with various environmental exposures and infectious agents, as well as family history. It is characterized by the presence of granulomas in the liver, lymph glands, bone marrow, brain, and most frequently, the lungs. Sarcoidosis is more prevalent in women and, in the United States, African Americans are both more commonly and more severely affected than Caucasians. Our studies, together with our collaborators at Henry Ford Health Systems, have identified a major genetic component on chromosome 5 unique to African Americans. Current studies focus on using ancestry-specific information to help elucidate the exact location of these genes.
