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.

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
