Association signals at 4 loci directly overlapped with other GWAS signals (r2 > 0.8 in 1KG CEU; from the National Human Genome Research Institute (NHGRI)), with the shorter sleep allele associated with higher BMI (FTO), increased risk of Crohn’s disease (NFKB1, SLC39A8, BANK1 region), febrile seizures and generalized epilepsy (SCN1A), and cardiometabolic risk (FADS1/2 gene cluster), and decreased risk of interstitial lung disease (MAPT/KANSL). Here, FTO is linked to Crohn disease.
