OMIA 001436-9823 : Non-shivering thermiogenesis, absence of in Sus scrofa

Mendelian trait/disorder: unknown

Considered a defect: yes

Year key variant first reported: 2006

Species-specific description: Berg et al. (2006) presented convincing evidence that the poor thermoregulation ability of piglets is due to the whole pig lineage having a disrupted form of the gene for uncoupling protein 1 (UCP1), which in other species "is exclusively expressed in brown adipose tissue and plays a crucial role for thermogenesis by uncoupling oxidative phosphorylation". Specifically, exons 3 to 5 have been deleted in domestic pigs and their near relatives (European wild boars, Bornean bearded pigs, wart hogs, and red river hogs), indicating that the disruptive mutation occurred around 20 million years ago.
