The melanocyte-stimulating hormone receptor gene (MCIR) is the major candidate gene for the chestnut coat color in horses since it is assumed to be controlled by an allele at the extension locus. MCIR sequences were PCR amplified from chestnut (e/e) and non-chestnut (EI-) horses. A single-strand conformation polymorphism was found that showed a complete association to the chestnut coat color among 144 horses representing 12 breeds. Sequence analysis revealed a single missense mutation (83Ser… 

GWAS Identifies a Region Containing the SALL1 Gene in Variation of Pigmentation Intensity Within the Chestnut Coat Color of Horses.

A genome-wide association study utilizing the relative shade ranking as the phenotype and using 268 487 single-nucleotide polymorphisms (SNPs) genotyped using the Affymetrix Equine 670k array identified a single significantly associated region on chromosome 3: SALL1.

Mutations in MC1R Gene Determine Black Coat Color Phenotype in Chinese Sheep

The results suggest that the mutations of MC1R gene are associated with black coat color phenotype in Chinese sheep.

Identification of the e allele at the Extension locus (MC1R) in Brazilian Creole sheep and its role in wool color variation.

It is concluded that MC1R is involved in the control of wool color in Brazilian Creole sheep, particularly the dark phenotypes, although a second gene may beinvolved in the expression of the white phenotype in this breed.

Mutation in the melanocortin 1 receptor is associated with amber colour in the Norwegian Forest Cat.

It is concluded that amber colour in NFCs is caused by a single MC1R allele called e, which has never been documented.

Coat colours in the Massese sheep breed are associated with mutations in the agouti signalling protein (ASIP) and melanocortin 1 receptor (MC1R) genes.

Massese is an Italian dairy sheep breed characterized by animals with black skin and horns and black or apparent grey hairs. Owing to the presence of these two coat colour types, this breed can be

Born blonde: a recessive loss‐of‐function mutation in the melanocortin 1 receptor is associated with cream coat coloration in Antarctic fur seals

A nonsynonymous mutation is identified that results in the substitution of serine with phenylalanine at an evolutionarily highly conserved structural domain and implies that hypopigmented individuals are unlikely to suffer disproportionately from inbreeding depression, and hence, there is no reason to believe that they are at a selective disadvantage in the wider population.

Copy Number Variation and Missense Mutations of the Agouti Signaling Protein (ASIP) Gene in Goat Breeds with Different Coat Colors

Genotyping and sequencing results, deviation from Hardy-Weinberg equilibrium, as well as allele copy number evaluation from semiquantitative fluorescent multiplex PCR, indicated the presence of copy number variation (CNV) in all investigated breeds.

The MC1R and ASIP Coat Color Loci May Impact Behavior in the Horse.

The findings illuminate a promising and novel animal model for future study of neuroendocrine mechanisms in complex behavioral phenotypes in the horse.

Polymorphisms in MC1R and ASIP Genes are Associated with Coat Color Variation in the Arabian Camel

These sequence variations at the MC1R and ASIP genes represent the first documented evidence of candidate polymorphisms associated with Mendelian traits in the dromedary.



Red coat color in Holstein cattle is associated with a deletion in the MSHR gene

A direct test for determining the presence of the recessive allele causing red coat color in black Holstein cattle was attempted, assuming that the molecular basis of the bovine coat color phenotypes determined at the extension locus was similar to the one in horses and mice.

The role of melanocyte-stimulating hormone (MSH) receptor in bovine coat color determination

Three alleles of the MSH-receptor gene found in cattle are reported, with the wild-type allele E+ producing a variety of colors, reflecting the possibilities for regulating the normal receptor.

Pigs with the dominant white coat color phenotype carry a duplication of the KIT gene encoding the mast/stem cell growth factor receptor

It is reported here that dominant white pigs lack melanocytes in the skin, as would be anticipated for a KIT mutation, and the presence of a gene duplication in white pigs is confirmed.

Variants of the melanocyte–stimulating hormone receptor gene are associated with red hair and fair skin in humans

The findings suggest that in humans, as in other mammals, the MC1R is a control point in the regulation of pigmentation phenotype and, more importantly, that variations in this protein are associated with a poor tanning response.

A linkage group composed of three coat color genes and three serum protein loci in horses.

The linkage of e and Es in the horse is proposed to be homologous to the loose linkage of the extension locus (e) and a cluster of esterase loci on chromosome 8 in the mouse, and on linkage group IV in the rabbit.

Agouti protein is an antagonist of the melanocyte-stimulating-hormone receptor

Agouti protein is used to demonstrate that agouti is a high-affinity antagonist of the MSH receptor and blocks α-MSH stimulation of adenylyl cyclase, the effector through which α- MSH induces eumelanin synthesis.

Identification of a mutation in porcine ryanodine receptor associated with malignant hyperthermia.

Haplotyping suggests that the mutation in all five breeds of lean, heavily muscled swine has a common origin, and the development of a noninvasive diagnostic test will provide the basis for elimination of the MH gene or its controlled inclusion in swine breeding programs.
