ABSTRACT
Urea cycle disorders (UCDs) are inherited metabolic diseases that lead to hyperammonemia. Severe hyperammonemia adversely affects the brain. Therefore, we conducted a nationwide study between January 2000 and March 2018 understand present status of UCD patients in Japan regarding diagnosis, treatments, outcomes. A total 229 with UCDs (126 patients: ornithine transcarbamylase deficiency [OTCD]; 33: carbamoyl phosphate synthetase 1 [CPS1D]; 48: argininosuccinate [ASSD]; 14: lyase [ASLD]; 8: arginase [ARG1D]) were enrolled study. Although growth impairment is common UCDs, discovered Japanese only slightly shorter than mean height general adult population Japan. Patients neonatal-onset more likely experience difficulty finding employment spouse; however, some late-onset employed married. Additionally, intellectual developmental disabilities, such as attention deficit hyperactivity disorder (ADHD) autism, hinder from achieving healthy social life.
