Mayo Clinic finds fatty liver disease is five distinct subtypes

· Science · United States

Mayo Clinic researchers report that metabolic dysfunction-associated steatotic liver disease, which affects nearly 30% of adults worldwide, is not one condition but five biologically distinct subtypes. Each subtype carries a different risk profile for liver failure, cancer, heart disease and other outcomes. The finding challenges the current practice of treating the disease as a single diagnosis and points toward subtype-specific risk assessment. The work was reported by ScienceDaily. Separate research items on a protein linked to the disease were not part of this study.

Why it matters：If confirmed, splitting the world's most common chronic liver disease into biological subtypes could reshape trial design, biomarker strategy and drug development for a market covering roughly a third of adults.

Key points

  • The disease affects nearly 30% of adults worldwide.
  • The five subtypes differ in risk for liver failure, cancer and heart disease.
  • Findings come from Mayo Clinic researchers.
