Analysis of novel ARG1 mutations causing hyperargininemia and correlation with arginase I activity in erythrocytes.
The panel of heterogeneous ARG1 mutations that cause HA was expanded, nevertheless a clear genotype-phenotype correlation was not observed, and bioinformatics analyses revealed that missense mutations affect the ARG 1 active site, interfere with the stability of the ARg1 folded conformation or alter the quaternary structure of theARG1.
