<jats:p>Rex rabbit, with multiple phenotypes and colourful fur, is an interesting model for assessing the effect of coat colour gene mutations on characteristic pigmentation phenotype.

We sequenced 1689 base pairs of the <em>MLPH</em> gene in Chinchilla and black Rex rabbit. A total of 13 polymorphisms were identified, including seven missense mutations. The rabbit <em>MLPH</em> gene has a very high GC content and the protein shows 64.87% identity to the orthologous human protein (lack of homologous amino acids encoded by human MLPH exon 9). Hardy-Weinberg test showed that, except for the g.606C&gt;A single nucleotid polymorphism (SNP), all other SNPs were in Hardy-Weinberg equilibrium.
