    Patients with metabolic dysfunction-associated steatotic liver disease (MASLD) can be classified into 5 distinct subgroups with unique genetic profiles.

  • 2

    The study analyzed data from 2,042 patients in the Mayo Clinic cohort and 2,560 patients in the Tapestry cohort to derive these subgroups.

  • 3

    C4, a polygenic subgroup, exhibited a mild metabolic profile but significant long-term liver risks, including fibrosis and cirrhosis.

  • 4

    C5 demonstrated a liver-dominant disease trajectory with increased risks for MASH, fibrosis, and acute renal failure compared to C1.

  • 5

    The classification of MASLD subgroups showed reproducibility across cohorts, indicating potential for individualized clinical management.
