Wilms tumour
In 1995, Vaiman et al. designed conserved primers from mouse and human sequence data, and successfully amplified a 150-bp fragment of the homologous gene in cattle, sheep and pig, which includes a dinucleotide (TG) microsatellite. Exploiting the polymorphism of the microsatellite, they were able to map the Wilms tumour gene to cattle chromosoem 15, between FSHB and NCAM, and possible near HBB.

Xanthinuria, type II
Cloning and sequencing of the bovine gene encoding molybdopterin cofactor sulfurase (MCSU, now called MOCOS) in normal and affected cattle, by Watanabe et al. (2000), revealed the causal mutation to be a 3bp deletion (c.769_771delTAC) of codon 257 (deleting Tyr) in the MOCOS gene (omia.variant:446). Murgiano et al. (2016) discovered a different mutation in the MUCOS gene as the likely cause in Tyrolean Grey cattle: "1 bp deletion in the molybd...
