The protein phosphatase 1 regulatory subunit 3B gene (PPP1R3B), which associated with liver attenuation, did not associate with MASLD histology (5) and was subsequently shown to promote liver glycogen storage, as opposed to hepatic steatosis, both of which affect liver attenuation (49). The gene discussed is PPP1R3B; the disease is metabolic dysfunction-associated steatotic liver disease.
