OMIA:002963-9031 : Feather colour, down, white in Gallus gallus (chicken)

Categories: Pigmentation phene

Single-gene trait/disorder: unknown

Disease-related: no

Cross-species summary: Down feathers are fine feathers found under the tougher exterior feathers and are the only feathers in young chicks.

Mapping: Kudinov et al. (2019) mapped day-old chick down feather colour in Russian White chickens to a region on chromosome 2.

Molecular basis: Yevshin et al. (2024) "identified an [Russian Snow White] RSW-specific missense mutation in the RALYL gene [chr2:122881444:G>T; p.(R643L)], presumably causing the snow-white color of the day-old chicks ... ."
