Generell informasjon
Coat colour in cats is controlled by a wide range of different genes working together. These genes are often referred to as “loci”. The C-Locus, a.k.a. Colour Locus, corresponds to the gene for tyrosinase (TYR). Recessive mutations to TYR can cause various degrees of Type 1 Oculocutaneous Albinism (OCA1), a failure to produce pigment, which leads to a silvery-white coat and light-coloured eyes. This can range between the distinctive point colouration of the Siamese cat, to full albinism.
The mutation analysed in this test, designated as “c2”, is one of two that results in a fully albino coat. Together with the “c” mutation, it is recessive to all other C-Locus alleles.
Kliniske egenskaper
Affected cats are fully albino, with a white coat, blue eyes and a reddish tapetal reflection.
Tilleggsinformasjon
Pelsfarge har en komplisert nedarving som involverer en kombinasjon av flere forskjellige gener. Testing for en rekke forskjellige loci vil gi den mest komplette prediksjonen av hundens pelsfargegenetikk.
