A team of researchers from Duke University Medical Center, the California Institute of Technology, the National Institute of Mental Health and Baylor College of Medicine has found via a new reporter that cholinergic neurons ...
The gene UBE3A plays a critical role in early neurological development. If UBE3A is overexpressed - or if the enzymatic function of UBE3A protein is hyperactive - autism ensues. A lack of functional UBE3A causes Angelman ...
