Mapping: Wilkinson et al. (2013) identified a region (31.74–33.78 Mb) on chromosome SSC5 making a major contribution to ear type.
Molecular basis: By closely examining the candidate region on chromosome SSC5, Chen et al. (2018) "identified a 38.7-kb copy number variation (CNV) that affects the last two exons of MSRB3" as a likely causal variant for ear size, and hence whether or not ears are folded. The authors reported that "The presence of this CNV results in an increase in the expression of [the microRNA] miR-584-5p, which inhibits the expression of its target gene MSRB3, which affects porcine ear size".

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.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
