WebNO synthase can metabolize L-arginine (ARG) to generate NO and L-citrulline (CIT). Two methylated ARG derivatives, asymmetric and symmetric dimethylarginine, are also involved in NO deficiency. Thus it was hypothesized that their combined ratios relate to blood pressure (BP) abnormalities in children with early CKD. ... WebNewborn screening results are also mailed to submitter.

WebCombined levels of orotic acid and citrulline in routine NBS can enhance the detection of UCD, especially increasing the screening sensitivity for OTCD and differentiate it from CPS1D. Our data and the negligible extra cost for orotic acid determination might contribute to the discussion on screening for proximal UCDs in routine NBS. Keywords ... WebCitrulline is needed to build arginine, which is an amino acid used in proteins. Citrulline is part of the urea cycle. Classic phenylketonuria.
