Researchers at The University of Texas at Austin have discovered that the lack of a critical enzyme in the folic acid metabolic pathway leads to neural tube birth defects in developing embryos.
Teaming Up Against Birth Defects: John Wallingford and Tim George work at different ends of the biomedical-health-care spectrum. Wallingford is a scientist doing basic research at The University of Texas at Austin. Using frogs and mice as models, he studies how embryos develop and what can go wrong in development. George is a pediatric neurosurgeon at Dell Children's Medical Center. Among his patients are children with birth defects.
