OMIA 002189-8932 : Wing pattern pigmentation in Columba livia

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 310600 , 305390

Mendelian trait/disorder: yes

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2018

Inheritance: Vickrey et al. (2018): "major wing shield pigmentation phenotypes are determined by an allelic series at a single locus (C, for ‘checker’ pattern) that produces four phenotypes: T-check (CT allele, also called T-pattern), checker (C), bar (+), and barless (c), in decreasing order of dominance and melanism"

Mapping: Vickrey et al. (2018) mapped the wing-pattern locus to "a single ~103 kb significantly differentiated region on Scaffold 68 that was shared by all checker and T-check birds (position 1,702,691–1,805,600 of the Cliv_1.0 pigeon genome assembly".

Molecular basis: Vickrey et al. (2018) "resequenced genomes of 9 barless pigeons and found that all were homozygous for a nonsynonymous protein-coding change at the start codon of NDP that was perfectly associated with the barless wing pattern phenotype . . . We genotyped an additional 14 barless birds and found that all were homozygous for the same start-codon mutation. The barless mutation is predicted to truncate the amino terminus of the NDP protein by 11 amino acids, thereby disrupting the 24-amino acid signal peptide sequence"

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.
