D-locus D1 (dilution)

The D-locus influences distribution of all pigments causing coat colour dilution. Common names... more
The D locus is the primary locus associated with diluted pigment. A recessive mutation is the cause of colour dilution phenotypes in the dog. Two alleles (variants) were described: the dominant full colour (D) and the recessive diluted colour (d). Two copies of dilute are needed to lighten black pigment to grey (often called blue), brown pigment to silver or isabella and red pigment to cream (also called buff). A diagnostic DNA test identifies the specific variants of the MLPH gene.
