Molecular Genetics

By cloning and sequencing a very likely comparative positional candidate gene (see the Genetic mapping section above), Seitz et al. (1999) reported that a missense mutation at 654 bp (amino acid 193, Ala>Asp) in the mast cell growth factor (MGF) locus is responsible for the roan phenotype in Belgian Blue and Shorthorn cattle (Mohammad Shariflou. The MGF gene is now called KITLG (10/11/2006; FN 15/9/2012)

Genetic Test

A PCR-RFLP was reported by Seitz et al. (1999).
