OMIA 002191-93934 : Feather colour, dilution in Coturnix japonica

Mendelian trait/disorder: yes

Considered a defect: no

Key variant known: no

Species-specific description: Ishishita et al. (2018): "The L strain of Japanese quail exhibits a plumage phenotype that is light yellowish in colour."

Inheritance: Ishishita et al. (2018): "The yellowish plumage was inherited in an autosomal recessive manner".

Mapping: Ishishita et al. (2018) mapped the yellowish locus to "an 810-kb genomic region of the LGE22C19W28_E50C23 linkage group (LGE22). This region contained the PMEL gene that is required for the normal melanosome morphogenesis and eumelanin deposition."

Molecular basis: Ishishita et al. (2018) "identified a nonsense mutation [g.811370G>A (NC_029544.1); Trp149*] in the premelanosome protein (PMEL) gene showing complete concordance with the yellowish plumage within a pedigree as well as across strains by genetic linkage analysis of an F2 intercross population"

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.
