A nonsense mutation in the tyrosinase gene causes albinism in water buffalo. Repositório Alice
DAME, M. C. F.; XAVIER, G. M.; OLIVEIRA FILHO, J. P.; BORGES, A. S.; OLIVEIRA, H. N.; RIET-CORREA, F.; SCHILD, A. L..
Background: Oculocutaneous albinism (OCA) is an autosomal recessive hereditary pigmentation disorder affecting humans and several other animal species. Oculocutaneous albinism was studied in a herd of Murrah buffalo to determine the clinical presentation and genetic basis of albinism in this species. Results: Clinical examinations and pedigree analysis were performed in an affected herd, and wild-type and OCA tyrosinase mRNA sequences were obtained. The main clinical findings were photophobia and a lack of pigmentation of the hair, skin, horns, hooves, mucosa, and iris. The results of segregation analysis suggest that this disease is acquired through recessive inheritance. In the OCA buffalo, a single-base substitution was detected at nucleotide 1,431 (G...

First report of partial albinism in genus Thrichomys (Rodentia: Echimyidae) Pap. Avulsos de Zool. (São Paulo)
Neves,Antonio Carlos da S.A.; Coutinho,Ludmilla Carvalho; Oliveira,Marcione B. de; Pessôa,Leila Maria.
Reports about albinism in rodents are common. In the family Echimyidae, however, albinism is very rare. This is the second case of coat color variation reported within Echimyidae and the first for the genus Thrichomys. The pelages of Thrichomys pachyurus individuals with normal and variant coat color were observed under a fluorescent artificial light and were examined with a stereoscopic microscope. The descriptions of pelage color were based on the book "Color Standards and Color Nomenclature". The predominantly white pattern of coat color in individuals of T. pachyurus suggests a partial albinism caused by delay in migration time of melanoblasts from neural crest to epidermis. The habitat of T. pachyurus has a heavy vegetative cover, which offers natural...

Identification of genes associated with shell color in the black-lipped pearl oyster, Pinctada margaritifera ArchiMer
Lemer, Sarah; Saulnier, Denis; Gueguen, Yannick; Planes, Serge.
Background: Color polymorphism in the nacre of pteriomorphian bivalves is of great interest for the pearl culture industry. The nacreous layer of the Polynesian black-lipped pearl oyster Pinctada margaritifera exhibits a large array of color variation among individuals including reflections of blue, green, yellow and pink in all possible gradients. Although the heritability of nacre color variation patterns has been demonstrated by experimental crossing, little is known about the genes involved in these patterns. In this study, we identify a set of genes differentially expressed among extreme color phenotypes of P. margaritifera using a suppressive and subtractive hybridization (SSH) method comparing black phenotypes with full and half albino individuals....
