Phenotypes
Coat colour, colour-sided — Color-sided
Fontanesi et al. (2010): "[V]ariation in the white spotting in several cattle breeds is largely influenced by the multiple allelic series at the S locus, which includes at least four alleles (Olson 1999): SH (Hereford pattern), SP (Pinzgauer pattern or lineback), S+ (non-spotted) and s (spotting pattern). The SH allele gives white face, belly, feet and tail, often with a white stripe over the shoulder when homozygous. The SP allele gives pigm...

Coat colour, roan
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)
Coat colour, white spotting, KIT-related — Hereford pattern or white headed, as well as spotting

Gonadal hypoplasia
This disorder is associated with white coat colour (Lauvergne, 1970).
