Molecular basis: Forcada et al. (2013) investigated the comparative and functional candidate gene MC4R in domestic shorthair cats. The authors identified a MC4R:c.92C>T variant in the gene and investigated an association with diabetes mellitus and overweight body condition score: "No significant differences in MC4R:c.92C>T allele or genotype frequencies were identified between nondiabetic overweight and lean cats." The association with the variant and overweight diabetic cats was significant (see OMIA:000284-9685 : Diabetes mellitus, type II in Felis catus). Jerjen et al. (2023) "assess the association between the previously described MC4R variant and body condition score (BCS), as well as body fat content (%BF) in 89 non-diabetic domestic shorthair cats. Furthermore, we investigated the feline POMC gene as a potential candidate gene for obesity. Our results indicate that the MC4R:c.92C>T polymorphism is not associated with BCS or %BF in non-diabetic domestic shorthair cats. The mutation analysis of all POMC exons identified two missense variants, with a variant in exon 1 (c.28G>C; p.G10R) predicted to be damaging. The variant was subsequently assessed in all 89 cats, and cats heterozygous for the variant had a significantly increased body condition score (p= 0.03) compared with cats homozygous for the wild-type allele."
