OMIA 001579-9823 : Ear size in Sus scrofa

Mendelian trait/disorder: no

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2011

Mapping: Major QTL for this trait were mapped on chromosomes SSC5 and SSC7 by Wei et al. (2007) and Ma et al. (2009).

Zhang et al. (2014) narrowed the QTL on SSC5 to a 450kb region containing two functional candidate genes, namely LEMD3 and WIF1.

Molecular basis: Ren et al. (2011) reported a G32E missense mutation in PPARD as the basis of the major QTL for ear size on chromosome SSC7.

Liang et al. (2019) reported a c.1167C>G missense mutation in WIF1 as the basis of the major QTL for ear size on chromosome SSC5.

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.
