OMIA 002217-9823 : Hyperphagia leading to hepatic steatosis in Sus scrofa

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 618406 , 618306

Mendelian trait/disorder: unknown

Considered a defect: yes

Species-specific description: This disorder is a result of creating "MC4R biallelic knockout pigs using CRISPR/Cas9" (Hao et al., 2019). This entry thus concerns a genetically-modified organism (GMO).

Clinical features: Hao et al. (2019) concluded "that deletion of MC4R results in hyperphagia and increased body fat, ultimately leading to hepatic steatosis without atherogenic diet."
