PHF2 and type 2 diabetes mellitus: In the first GWAS targeting youth-onset diabetes in a multi-ethnic cohort (non-Hispanic White, African American and Hispanic) with an age of diagnosis <20 years and a mean age of 15 years, researchers identified seven genome-wide significant loci, including one novel signal in PHF2 (encoding for PHD finger protein 2) not reported to be associated with type 2 diabetes in adults [9].
