This systematic review and meta-analysis examined the association between the PNPLA3 rs2896019 polymorphism and metabolic dysfunction-associated steatotic liver disease (MASLD) in adults. Analyzing data from 10 case-control studies with 15,028 participants, the G allele was found to increase MASLD risk by 51% (OR: 1.5, CI: 1.23-1.85, P < 0.0001), with a stronger association in biopsy-proven cases.

Key findings

  • The G allele of PNPLA3 rs2896019 is associated with a 51% increased risk of MASLD (OR: 1.5, CI: 1.23-1.85, P < 0.0001).
  • A gene-dose effect was observed, with homozygous individuals showing an OR of 2.32 for MASLD (95% CI: 1.53-3.53, P < 0.0001).
  • The G allele significantly increased the risk of severe MASLD/MASH (OR = 2.06) compared to mild steatosis (OR = 1.40).

Why it matters

Understanding genetic risk factors for MASLD can help clinicians identify high-risk patients and tailor monitoring and management strategies. The findings underscore the importance of genetic screening in assessing MASLD susceptibility and severity.
