Evaluation of Newborn Screening for Diseases Using C5-OH as a Marker: Systematic Review of the Literature and Evaluation of 17 Years of C5-OH Screening in the Netherlands.

ABSTRACT: In 2007, the Dutch newborn screening (NBS) program was expanded to include C5-OH as a marker to screen for three inborn errors of metabolism (IEMs): 3-methylcrotonyl-CoA carboxylase deficiency (3-MCCD), 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (HMGCLD) and holocarboxylase synthetase deficiency (HLCSD). This study evaluates the effectiveness of C5-OH as an NBS marker by analyzing data from neonates screened in the Dutch NBS program from 2007 to 2023 and by reviewing the literature on various IEMs detected by an elevated NBS C5-OH concentration worldwide. Of the 126 neonates referred on the basis of elevated C5-OH concentrations in the Netherlands, 46 were true positive cases. No missed cases in the Netherlands have been reported so far, resulting in a positive predictive value of 38.
