Case Previous Testing: "Genomic DNAs were extracted from leukocytes, The ten exons and intron-exon boundaries of the OTC gene were PCR amplified and analyzed by Sanger sequencing on an ABI3100 sequencer. Intragenic deletions/duplications were searched for by Multiple Ligation Probe Dependent Amplification assay. Potential impact of non truncating variants on mRNA and protein was predicted using Splice Site Prediction. OTC variants were split into two groups, “severe” and “mild,” based on their impact on the clinical phenotype and on the OTC protein.

Supplemental Data: Table 3, All nuclear family members were tested but no information about their genotype. the condition to be part of this study was the presence of at least one heterozygous female in the pedigree of the patient.
