Case Previous Testing: The OTC gene mutations were identified using PCR amplification, classical sequencing (Sanger), and multiplex ligation-dependent probe amplification.10,11 Mutations were identified by comparison with the GenBank reference sequence for human OTC (GenBank entries: NG_008471.1, NP 000522.3, NM 000531.5, NC 000023.11) Missense mutations were analyzed using different computational algorithms: CLUSTALW2 (http://www.clustal.org/clustal2/), SIFT (http://blocks.fhcrc.org/sift/SIFT.html),Polyphen2(http://genetics.bwh.harvard.edu/pph/),PoPMuSiC(http://babylone.ulb.ac.be/popmusic/), and SIFT Indel(http://siftdna.org/www/SIFT_indels2.html).
