The Heritable Liver Disease Genetic Testing Service is a collaboration between the Molecular Genetics Laboratory and Jorge Bezerra, MD, a pediatric gastroenterologist and developer of the JaundiceChip Resequencing Array, at Cincinnati Children's Hospital Medical Center. This partnership allows for optimum care of your patients.
We are staffed by a team of experts who provide guidance in:
Clinical interpretations are written in conjunction with our nationally recognized pediatric gastroenterologist, board-certified molecular and medical geneticists and genetic counselors. Each report is customized for your patient and includes a detailed interpretation of the genetic findings, the clinical significance of the results and the specific recommendations for clinical management and additional testing, if warranted. These specialists are also available to you for pretest or additional post-test consultation.

Jorge A. Bezerra, MD, joined the Cincinnati Children's Hospital Medical Center Division of Gastroenterology, Hepatology and Nutrition in 1990, when he began his fellowship training in pediatric gastroenterology and nutrition and graduated in 1993.
From 1992-1994, Dr. Bezerra was a research scholar in the Division of Basic Sciences. He was appointed to the division in 1994 as an assistant professor of pediatrics.
Dr. Bezerra completed his residency in pediatrics at the University of Arizona in Tucson, Arizona.
Dr. Bezerra has an active research career with his primary interests in molecular control of liver regeneration, biliary atresia, and genetic basis of intrahepatic cholestasis.
In addition to his research work, Dr. Bezerra is an active clinician for the outpatient GI clinical service and the inpatient liver service.
