Case Previous Testing: GDNA from blood, cultured skin fibroblasts, liver from patients suspected for otc deficiency was used to amplify all 10 exons and exon/intron boundaries using primers listed in Table 1. The amplified DNA fragments were then screened by single-strand conformational polymorphism (SSCP) and the abnormally migrating DNA fragments were sequenced directly from PCR products (w/o subcloning) to identify the mutation. The amino acid residue substitution created by the mutation is examined using an alignment of 26 OTCase sequences from 23 species.
