Mutations in the Grb10-interacting GYF protein 2 (GIGYF2) gene, within the PARK11 locus, have been nominated as a cause of Parkinson's disease in Italian and French populations. By sequencing the whole GIGYF2 coding region in forty-six probands (thirty-seven Italians) with familial Parkinson's disease compatible with an autosomal dominant inheritance, we identified no mutations. Our data add to a growing body of evidence suggesting that GIGYF2 mutations are not a frequent cause of PD.
