603470.0009; CITRULLINEMIA |
| Identified Mutation |
GLY390ARG; Kobayashi et al. (1989) demonstrated a change in codon 390 in the ASS gene, GGC (gly) to AGG (arg), in a case of citrullinemia (215700). Five of the 6 single base mutations involved C:G to T:A transitions in CpG dinucleotides.
In a review, Engel et al. (2009) stated that the G390R mutation is the most common mutation in patients with the classic phenotype of citrullinemia.

| Remarks |
Clinically affected; diagnosed by newborn screening (citrulline 960); developmental delay/mental retardation; past hyperammonemic events; normal neurological evaluation at age 5; donor subject has a G>A transition at nucleotide 1168 in exon 15 of the ASS1 gene (1668G>A) resulting in the substitution of arginine for glycine at codon 390 [Gly390Arg (G390R)]; treatments include: protein restriction. |
