OMIA 001128-9823 : Pale soft exudative meat in Sus scrofa
Liu et al. (2019) investigated the occurrence of pale, soft and exudative meat in Luchuan X Duroc pigs. After excluding the well-known mutations in RYR1 and PRKAG3 they identiﬁed that the PHKG1 splice variant identified by Ma et al. (2014) caused PSE meat in this crossbred population.Prevalence: Ma et al. (2014): “The unfavorable allele exists predominantly in Duroc-derived pigs.” Breed: Duroc. Associated gene:

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.
