Oculocutaneous hypopigmentation (OH) is a non-lethal genetic condition recognised in 2016.
The condition, which is largely considered to be cosmetic in nature, produces calves with pale blue irises and tan periphery. The coat on affected calves has a slightly bleached appearance and calves may be sensitive to light.
OH is controlled by a simple recessive mutation.
There have been no cases of OH reported in Australia to date.
