Genetic differences play an important role in normal human development and disease. These differences can also play a role in the progression of disease and in individual responses to therapy. The research mission of our laboratory is to use of modern genomics to help understand the roles of human genetic variation in these processes.
Genetic variation in human populations. We have characterized genetic variation in a number of human populations (Hispanics and Latinos, Jewish HapMap Project) to understand the origins and migrations of these populations. Currently, we are exploring the role of natural selection in the formation of some of these populations. We are carrying the work forward to understand disease susceptibilities within these groups. A key feature of this work is translating new findings into clinical practice to promote personalized medicine
Human developmental disorders. We study the genetic basis of rare genetic disorders, notably disorders found in isolated populations and disorders of sex development, to indentify not only the mutational basis, but also the molecular mechanisms. Recently, we identified mutations in genes in the MAP kinase pathway in abnormal testicular development and now are investigating the roles of members of this pathway in normal testicular development.
Cancer genetics and genomics. We have explored the roles of low and high-penetrance variants in risk of human cancers and have developed models for predicting risk. Through genome wide association studies, we have identified common variants that increase risk of adverse outcomes (erectile dysfunction, urinary dysfunction, proctitis) for men treated with radiation therapy for prostate cancer. We have also developed a molecular signature based on acquired somatic copy number alterations that is highly predictive of risk of metastasis and may account for this increased risk among African-American men.
