Follow-up study of the GIGYF2 gene in French families with Parkinson's disease

Abstract

Meeus et al. (2009) reported no pathogenic mutations in a comprehensive genetic analysis of the entire GRB10-interacting GYF protein-2 gene (GIGYF2) in a Belgian series of both familial and sporadic patients with Parkinson's disease (PD). Although we initially proposed that GIGYF2 corresponds to the PARK11 locus, in familial PD, we found no causative variations in a follow-up study in which GIGYF2 was screened in an independent series of 185 patients with autosomal dominant PD, mostly of French origin. Together, these results do not support a major role of GIGYF2 in PD.
