A genetics research team has solved a dilemma facing researchers who use genomewide association studies (GWAS) by developing a new approach that strategically ‘filters’ which genes are worth further study. The researchers hope this strategy will accelerate the study of diseases such as Parkinson’s, Alzheimer’s, schizophrenia and even addiction by helping researchers avoid ‘dead-end paths.’ They are optimistic that this strategy will gain widespread use and will save researchers time and money.
