    1. Case: patient #5, male, German Disease Assertion: UCD/OTCD

      Family Info: Family history of the disease, Variant found in mother of the patient

      Case Presenting HPOs: infantile onset (HP:0003593), oritic aciduria(HP:0003218), hyperammonemia(HP:0001987), hyperglutaminemia(HP:0003217), low plasma citrulline (HP:0003572)

      Case Previous Testing: Liver tissues were used to extract RNA that was later used to synthesize cDNA. The products were compared to healthy controls in order to detect variants. gDNA, in order to determine the size of deletions in patient 3 and 4 , a set of intronic primers presumably flanking the deletions was used and specific primers allowed sequencing of exactly those critical regions(sequencing on paper). To estimate the relevance of the identified intronic variants in terms of their capability to induce splicing, we used a score developed by Shapiro and Senapathy. This splice score offers information about the usage of a certain splice site
