Replicating genotype–phenotype associations.

The article presents a replication study that evaluates the previous study on genotype-phenotype associations. The study concentrates on the initial discoveries which limit the plethora of false-positive results and determines the valid associations of genotype-phenotype. Three topics were addressed by the investigators, including the assessment of the validity and limitations of any genetic association, criteria for establishing the replication, and publication of high-quality association.
