ARG23TER |
| Remarks |
Clinically affected; elevated orotate after allopurinol challenge with absence of argininosuccinic acid (elevated orotic acid = 759); past hyperammonemic events; on citrulline arginine supplement, sodium benzoate and sodium phenylbutyrate; protein restriction; neurologic evaluation was normal at age 1 year; donor subject is heterozygous for a C>T transition at nucleotide 67 in exon 1 of the OTC gene (67C>T) resulting in a stop at codon 23 [Arg23Ter (R23X)] |
