Albinism is a genetic condition that results in a lack of pigmentation in the skin, hair, and eyes of animals, including cats. Cats with albinism have a striking appearance, with white fur and bright blue eyes, but they can also be prone to certain health issues. Albinism in cats Albino cats are not just white cats. This state is caused by a gene that is called TYR. This gene will determine the presence of an enzyme called tyrosinase that is needed for cats to produce melanin. If a cat misses a TYR gene, she will be an albino cat. A lack of melanin will make a cat albino. Albino cat vs. white cat

Albinism is a genetic condition in which there is a complete lack of color or pigmentation. For a kitten to be born a true albino cat, both the mother and father must carry the genetic marker. Albinism is caused by a gene called TYR. The TYR gene determines the presence of tyrosinase, an enzyme needed by the body to produce melanin. Melanin is the pigment that decides the color of a cat's eyes, skin, and fur. An albino cat is born with a damaged or missing TYR gene. This genetic abnormality and lack of melanin is what makes a cat albino. Hereditary Hair Loss (Alopecia) Skin Color (Pigmentary) Abnormalities Defects of Structural Integrity Congenital and Inherited Tumors Cats can be born with or may inherit several different kinds of skin abnormalities. Some inherited skin disorders can become visible weeks to months after birth. Most of these conditions are uncommon to rare. Albinism is a genetic condition that results in a lack of pigmentation in the skin, hair, and eyes. In cats, the condition is caused by a mutation in one of several genes responsible for producing melanin, the pigment that gives color to the hair, skin, and eyes.
10 Adorable Photos Of Albino Cats
The typical "points" of siamese and burmese cats result from a temperature-sensitive form of albinism, in which eumelanin pigment develops only in the cooler extremities, such as ears, paws, and tail. The degree of darkness of these features is determined by the exact form of eumelanin, which is determined by a series of four alleles: Albinism is defined as a genetic condition that results in an entire lack of pigmentation. This lack of pigment can be seen in both humans and animals — and in this case, cats. Other than a white coat, albino kittens and cats will also have no coloration in their skin and eyes. What Exactly is an Albino Cat? gatitas_nevadas Albino Home DNA Tests Cat Albino Quick Summary The feline albino mutation is a rare mutation that produces a white coat with blue eyes, and is recessive to the sepia and Siamese mutations. Click here for Price and Turnaround Time Phenotype: The albino mutation produces a white coat with blue eyes. Mode of Inheritance: Autosomal recessive Summary Albino phenotypes are documented in a variety of species including the domestic cat. As albino phenotypes in other species are associated with tyrosinase ( TYR) mutations, TYR was proposed as a candidate gene for albinism in cats.

Albinism is a congenital disorder that is characterized by lack of pigment in hair, skin and eyes. Recently, the causative mutations for the siamese and burmese temperature-sensitive alleles have been identified in tyrosinase (TYR; Lyons et al. 2005).Complete albinism in cats is hypothesized to be caused by an additional allele at TYR, contributing to the allelic series at the colour (C) locus. A kitten that is born with a damaged or missing TYR gene is considered to be albino. Again, this can only happen if both parents carry the gene that is defective, and they will then pass it on. Not only does melanin play a role in the color of the fur and eyes, it also helps to protect animals from the harsh rays of the sun.
Characteristics of an albino cat. Albinism is caused by a genetic mutation responsible for the coding of tyrosinase, the main enzyme in the production of melanin. Studies comment that some gene mutations that influence coloration patterns (such as albinism) have been introduced to wild populations by the movement of genes from one species to. Complete albinism (c a c a ), is recessive to all other alleles and is characterized by a completely white coat color and has been identified in the Siamese breed.

Albinism is the result of a genetic mutation: the tyrosinase (TYR) mutation. This gives cats white fur and blue eyes. Experts have found that only about two percent of all cats are albino. However, mutations in the tyrosinase mutation can also lead to partial albinism and cause cats to have colorpoint coats (e.g., Siamese and Burmese). Albinism appears to be rare in domestic animals. True albinism is always associated with pink or pale irises and with visual defects and increased risk of solar radiation-induced neoplasms of the skin. It has been noted in Icelandic sheep and in Guernsey, Austrian Murboden, Shorthorn, Brown Swiss, and Charolais cattle.
