New research from Jason Yi, PhD, assistant professor of neuroscience at Washington University School of Medicine in St. Louis, has found in mice that the missing UBE3A gene is the first domino in a biological sequence that leads to a normally harmless enzyme accumulating in the brain. The buildup is not harmful on its own but appears to have indirect effects that ultimately impair brain growth.
