Dr. Garry R. Cutting is the Aetna/U.S. Healthcare Professor of Medical Genetics, Pediatrics and Medicine in the McKusick-Nathans Department of Genetic Medicine of the Johns Hopkins University School of Medicine. He has been the Medical Director of the DNA Diagnostic Laboratory of Johns Hopkins Genomics since 1995. He directed the Medical Genetics Residency Program at Hopkins from 1995 to 2004 and Clinical Genetic Laboratory Training Program from 1995 to 2018. As Editor of the journal Human Mutation, Dr. Cutting oversees the review and publication of manuscripts reporting the mechanism, distribution and phenotype consequences of variation in our genomes. Dr. Cutting has been very active in the Human Variome Project, an international effort to document all variation in human DNA (Board of Directors (2016-present), Co-Chair of the Board (2018-present), Co-Chair of the International Scientific Advisory Committee (2015-present) and Chair of the Reporting of Sequence Variants Working Group (2018-present)). Dr. Cutting’s primary research interests lie in the interpretation of DNA variation and their effect upon human phenotypes. Dr. Cutting’s lab focuses on the effect of common and rare variants in the CFTR gene that cause the single gene disorder cystic fibrosis (CF). His team operates the CFTR2 database, a resource composed of clinical and genetic data on almost 90,000 individuals with CF world-wide. His laboratory also studies the effect of clinically approved and novel modulators upon CFTR protein bearing disease-causing variants. Dr. Cutting’s laboratory is a leader in the identification and characterization of genetic modifiers of CF. His group is currently collaborating with teams at UNC and UW, Seattle to identify common and rare modifier variants of disease severity by whole genome sequencing.
