概要 | Late-onset Ornithine transcarbamylase deficiency (OTCD) manifests after the neonatal period. This study aimed to evaluate the pre-symptomatic blood citrulline levels in patients with late-onset OTCD.Patients with late-onset OTCD who were born after the newborn screening based on tandem mass spectrometry (MS/MS-NBS) was started and were referred to Hyogo College of Medicine Hospital between 2014 and 2018 were included. Four patients were included in this study. The pre-symptomatic blood citrulline levels were 2.02, 4.50, 4.97, and 3.75 µmol/l, respectively. Compared with the citrulline levels in all newborns in Hyogo prefecture, these values were significantly low. These results suggest the possibility that hypocitrullinemia detected by the MS/MS-NBS can be used as a screening marker for some patients with late-onset OTCD. |
