Spectrum analysis of inborn errors of metabolism for expanded newborn screening in a northwestern Chinese population
Abstract Expanded newborn screening facilitates early identification and intervention of patients with inborn errors of metabolism (IEMs), There is a lack of disease spectrum data for many areas in China. To determine the disease spectrum and genetic characteristics of IEMs in Xi'an city of Sha...
