This study identifies genetic heterogeneity in ulcerative colitis by analyzing genome-wide associations in mild and severe cases, finding distinct risk variants and a genetic risk score with no difference between mild and severe disease.

This study investigates how gut microbiota influences neural dynamics in threat processing by combining neuroimaging, 16S rRNA profiling, and computational modeling in healthy participants.

This paper identifies novel pleiotropic risk loci for melanoma and nevus density, implicating multiple biological pathways and gene expression under MITF regulation.
