Mutations and common variants in the human arginase 1 (ARG1) gene: Impact on patients, diagnostics, and protein structure considerations.

Abstract excerpt

The urea cycle disorder argininemia is caused by a defective arginase 1 (ARG1) enzyme resulting from mutations in the ARG1 gene. Patients generally develop hyperargininemia, spastic paraparesis, progressive neurological and intellectual impairment, and persistent growth retardation. Interestingly, in contrast to other urea cycle disorders, hyperammonemia is rare. We report here 66 mutations (12 of which are...
