EIF4G1 mutations do not cause Parkinson's disease

EIF4G1 mutations were previously reported as a cause of Parkinson's disease (PD). As a result of this finding, considerable work has been performed to test this idea and to examine the functional role of eukaryotic translation initiation factor 4-gamma in the pathogenic process underlying PD. Here, we show that the originally described mutation is likely a rare benign variant. We tested this variant in a very large series of subjects and show that it is more frequent in controls than cases. We argue here that this infers that EIF4G1 mutations are not related to PD.
