Two novel (G390V and X439W) and five already known mutations were identified in a total of 14 GA I alleles from Italy and Portugal. The substitution X439W is a rare type of mutation, which breaks the stop codon of the GCDH gene. As described in other populations, R402W was the most common mutation. Genotype R227P/R402W was found in a patient with low glutarate excretion. Haplotype studies have also been performed.
