OMIA:000375-8839 : Feather colour, white spotting, EDNRB2-related in Anas platyrhynchos (Mallard)

In other species: rock pigeon , Japanese quail

Categories: Pigmentation phene

Mendelian trait/disorder: yes

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2016

Cross-species summary: Renamed from 'Feather colour, panda/dotted white' [12/08/2023], also called piebald

Species-specific name: Spot plumage pattern

Molecular basis: Li et al. (2016): "The c.995G>A mutation, which results in the amino acid substitution of Arg332His, was completely associated with the spot phenotype". Xi et al. (2021) "revealed that EDNRB2 was the gene responsible for the variation in duck body surface spot size. Chr4: 10,180,939 T > C was the major allele that explained 49.5 % (dorsal side) and 32.9 % (ventral side) of the variation in duck body surface spot size, while 32.1 % (dorsal side) and 19.1 % (ventral side) of the variation could be explained by Chr4: 10,190,671 A > T."
