ABSTRACT=Inborn errors of metabolism (IEMs) are strongly related to the abnormal growth and development of newborns and can even result in death. In total, 94,648 newborns were enrolled for expanded newborn screening using tandem mass spectrometry from 2016 to 2020 at the Neonatal Disease Screening Center of the Maternal and Child Health Hospital in Shaoyang City, China. Twenty-three confirmed cases were detected in our study with an incidence rate of 1:4,115. Ten types of IEM were identified, and the most common IEMs were phenylalanine hydroxylase deficiency (1:15,775) and primary carnitine deficiency (1:18,930). Mutations in PAH and SLC22A5 were the leading causes of IEMs. To evaluate the application effect of artificial intelligence (AI) in newborn screening, we used AI to retrospectively analyze the screening results and found that the rate of false positives could be decreased by more than 24.9% after using AI. Meanwhile, a missed case with neonatal intrahepatic cholestasis citrin deficiency was found, the infant had a normal citrulline level (31 μmol/L; cut-off value of 6–32 μmol/L) indicating that citrulline may not be the best biomarker of intrahepatic cholestasis citrin deficiency. Our results indicated that using AI in newborn screening could improve efficiency significantly. Hence, we propose a novel strategy that combines expanded neonatal IEM screening with AI to reduce the occurrence of false-positives and false-negatives.
