To investigate shared genetic and molecular mechanisms, we tested genetic overlap (i.e., shared risk alleles) of MaxAlc with a wide range of phenotypes. Genetic correlations were calculated using the LD score regression method (https://github.com/bulik/ldsc) (24). LDSC results regarding 232 traits were extracted from the data available at LD Hub v1.4.0 (http://ldsc.broadinstitute.org/ldhub/)(25). Genetic correlations for an additional 1,547 traits were calculated using the GWAS summary association results available at https://sites.google.com/broadinstitute.org/ukbbgwasresults; these GWAS used data from ~337,000 unrelated British individuals from the UK Biobank (26).
