Dr. Gail Tomlinson, MD, PhD joined UT Health San Antonio in 2007 as the Division Chief of Pediatric Hematology-Oncology and currently also serves the Mays Cancer Center as co-Director of the Population Science and Prevention Program. Since her arrival, Dr. Tomlinson also served as Interim Director of the GCCRI and Interim Chair of the Department of Pediatrics.

Dr. Tomlinson received her MD from George Washington University School of Medicine and her PhD in Biochemistry from Duke University. She completed an internship and residency at the Children’s National Medical Center in Washington, D.C., and did a research fellowship in cancer genetics at the University of Texas MD Anderson Cancer Center in Houston, followed by a formal fellowship in pediatric hematology-oncology at the University of Texas Southwestern Medical Center in Dallas. Dr. Tomlinson was a faculty member at the University of Texas Southwestern Medical Center from 1992 to 2006, where was a tenured Associate Professor and held the Children’s Cancer Fund Distinguished Professorship in Pediatric Oncology Research. She currently is the holder of the Greehey Distinguished Chair in Cancer and Genetics.

Dr. Tomlinson is board certified in pediatrics and pediatric hematology-oncology. Her research interests are in the genetic origins of childhood cancers, particularly tumors of the liver. She leads a multi-site program working with cancer-prone individuals and families throughout South Texas. She has also initiated an investigation of predisposing factors underlying the increased incidence of leukemia in children of Hispanic background in South Texas. She has served on multiple national and state committees focusing on advancing research, education, and advocacy in childhood cancer and has published over 180 scientific papers. She currently is a member of the National Cancer Institute’s Board of Scientific Counselors.

Lab Research

  • GRACIAS Texas  Genetic Risk Assessment and Counseling iAll South Texas

    A grant from the Cancer Prevention and Research Institute of Texas has enabled us to provide genetic counseling services to multiple sites in South Texas, including our regional campuses in Laredo and Harlingen. To date, we have had direct interaction with a cancer risk assessment of over 8500 individuals and provided formal genetic counseling services to more than 1200 individuals, most of whom have undergone molecular genetic testing as part of our program.

    Our pediatric component of the genetic risk assessment is located at University Hospital.

  • Childhood Cancer Data Initiative: National Childhood Cancer Registry Data from South and West Texas Minority and Underserved Populations.
  • Novel strategies for the treatment of liver cancer in children.
  • Evaluating Utility and Improving Implementation of Genomic Sequencing for Pediatric Cancer Patients in the Diverse Population and Healthcare Settings of Texas: The KidsCanSeq Study (Collaboration with. Baylor College of Medicine).
  • Predictive Biomarkers and Novel Therapies in High-Risk Pediatric Liver Cancers (Collaboration with. Baylor College of Medicine)

Current Research:

  • Genetic Risk Factors and Admixture in Hispanic children with Acute Lymphoblastic Leukemia (ALL) from South Texas and Puerto Rico
    As not all populations identifying as Hispanic/Latino are genetically similar, the project led by pediatric hematology-oncology fellow, Dr. Sam Pabon, will investigate genetic similarities and differences in children with leukemia from Puerto Rico as compared to our population of children with leukemia in Texas.
