AOPEP and Dystonia: AOPEP gene has recently been linked to DYT31 causing multifocal or generalised dystonia.3 The pathogenic variant (p.G686EfsTer17) identified in our study is localised in the C-terminal outside of the putative active domains and leads to the early adulthood-onset dystonia, suggesting that the position of the pathogenic variants in the AOPEP gene does not change the impact on the dystonia pathogenesis.
