Abstract Background The coat colour of fallow deer is highly variable and even white animals can regularly be observed in game farming and in the wild. Affected animals do not show complete albinism but rather some residual pigmentation resembling a very pale beige dilution of coat colour. The eyes and claws of the animals are pigmented. To facilitate the conservation and management of such animals, it would be helpful to know the responsible gene and causative variant. We collected 102 samples from 22 white animals and from 80 animals with wildtype coat colour. The samples came from 12 different wild flocks or game conservations located in different regions of Germany, at the border to Luxembourg and in Poland. The genomes of one white hind and her brown calf were sequenced. Results Based on a list of colour genes of the International Federation of Pigment Cell Societies (http://www.ifpcs.org/albinism/), a variant in the MC1R gene (NM_174108.2:c.143 T > C) resulting in an amino acid exchange from leucine to proline at position 48 of the MC1R receptor protein (NP_776533.1:p.L48P) was identified as a likely cause of coat colour dilution. A gene test revealed that all animals of the white phenotype were of genotype CC whereas all pigmented animals were of genotype TT or TC. The study showed that 14% of the pigmented (brown or dark pigmented) animals carried the white allele. Conclusions A genome-wide scan study led to a molecular test to determine the coat colour of fallow deer. Identification of the MC1R gene provides a deeper insight into the mechanism of dilution. The gene marker is now available for the conservation of white fallow deer in wild and farmed animals.

SummaryModern pig breeds in Europe owe their origin to a mixture of Asian and European breeds and types. They evolved during the past two hundred years, and developed particular breed characteristics by the application of breed standards, which included specific reference to colour. DNA markers at two coat colour loci provide the potential for accurate breed assignation for wild boar, Berkshire and Tamworth breeds, and may also offer the potential to develop simple tools for the verification of the origin of pork products. The use of polymorphisms in genes determining coat colour is used to explore this potential in terms of breed identification for conservation of animal genetic resources, and product traceability for quality assurance.

Lysosomal Glycosidases

SUMMARYA spontaneous autosomal mutation in C57BL/Tb mice, provisionally called reduced pigmentation, symbol rp, has pronounced effects on three kidney lysosomal glycosidase activities. Homozygous rprp mice have significantly higher activities of β-galactosidase, β-glucuronidase and N-acetyl-β-hexosaminidase than their heterozygous litter-mates. Homozygotes have light ears and tails, diluted fur and dark eyes. The mutation is not allelic to any known to affect lysosomal functions, or to a number of pigmentation variants with similar phenotypic effects. The locus is on chromosome 7.
