The PNPLA3 SNP rs738409:G allele is associated with increased liver disease-associated mortality but reduced overall mortality in a population-based cohort

Published:December 11, 2017DOI:https://doi.org/10.1016/j.jhep.2017.11.038
      In a recent issue of the Journal, Atkinson and co-workers reported that a variant in the gene patatin-like phospholipase domain-containing 3 (PNPLA3) not only affects liver disease susceptibility but also mortality following episodes of severe alcoholic hepatitis.
