MIDN and Parkinson disease: However, using whole genome sequencing and analysis of a public database of structural variants, Billingsley et al. and the International Parkinson’s Genomics Consortium did not identify PD-associated midnolin deletions and disputed the determination of midnolin as a PD risk gene, indicating that further study with orthogonal methods is required to investigate midnolin association with PD and resolve controversy (Billingsley et al., 2020).
