To validate these findings, we analyzed a functionally suggestive FTO variant (rs1421085) in a separate cohort, examining its impact on (i) alcohol use based on the Alcohol Use Disorders Identification Test (AUDIT), (ii) subjective well-being based on the WHO (Ten) Well-Being Index, and (iii) neuroticism based on Schafer’s Five Factor Model or the Karolinska Scales of Personality. Here, FTO is linked to alcohol abuse.
