Species-specific description: Derks et al. (2018) suspect that the form of Z-linked feathering described in this OMIA entry "differs from a late feathering phenotype that was described in turkey by Asmundson and Abbott [1960]"

History: This trait was first reported by Zakrzewska and Savage (1997)

Inheritance: As in chickens, the locus is Z-linked, and slow-feathering is dominant to fast or rapid feathering (the wild type) (Zakrzewska and Savage, 1997)

Mapping: Via a GWAS of SNPs called from whole-genome sequencing of 12 slow-feathering and 12 fast-feathering turkeys from a commercial line, Derks et al. (2018) mapped this trait to "the short arm of the Z chromosome between 7.95 and 9.79 Mb"

Molecular basis: Derks et al. (2018) "identified a 5-bp frameshift deletion in the prolactin receptor (PRLR) gene that is responsible for slow feathering at hatch. All female cases (SF turkeys) were hemizygous for this deletion, while 188 controls (FF turkeys) were hemizygous or homozygous for the reference allele. This frameshift mutation introduces a premature stop codon and six novel amino acids (AA), which results in a truncated PRLR protein that lacks 98 C-terminal AA . . . this truncated PRLR protein is strikingly similar to the protein encoded by the slow feathering K allele in chicken." (see OMIA:000380-9031)

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.
