To the Editor A recent study1 in JAMA Neurology advanced the notion of next-generation phenotyping. Grünewald et al1 systematically evaluated the quality of published genetic and phenotypic data concerning parkin-associated Parkinson disease cases by adopting an ad-hoc score combining both genetic and clinical criteria. Interestingly, they found that while the quality of genetic analyses continuously increased over the last 15 years, the quality of retained clinical data stayed stable over time. Therefore, they proposed mandatory minimal criteria aimed at improving data acquisition and reporting in genotype-phenotype correlation studies. This is of crucial interest in both research and clinical settings in neurology as well as in all other medical domains.
