Background: Citrullinemia type 1 (CTLN1) is an autosomal recessive metabolic disease caused by ASS1 gene mutations encoding argininosuccinic acid synthase enzyme which is within the pathway of arginine and nitric oxide biosynthesis.
Methods: Disease confirmation was done by ASS1 gene mutation analysis using Next Generation Sequencing, DNA Sanger sequencing and bioinformatics. The study group members were17 citrullinemia type1 patients from 10 unrelated families referred to Iranian National Society for the Study of Inborn Errors of Metabolism’s clinic between 2008-2020. Clinical, laboratory and molecular data were retrospectively evaluated.
Results: Eleven different ASS1 gene mutations were detected. Presentation: 3/17 (76%) neonatal, 3/17 (18%) late infantile, 1/17(6%) asymptomatic. Severe developmental delay.. View More»
