Genetic Condition Policy

Genetic abnormalities are a reality for any living organism, and the understanding of these conditions continues to evolve with scientific advancements.

Leading geneticists in the bovine academic community have increasingly observed that all breeds have hundreds of mutations in their genome. The American Angus Association's approach to genetic conditions reflects the likelihood that the discovery of such mutations will continue in the future and at a pace accelerated by new scientific tools.

The Association relies on sound scientific principles to determine policy governing genetic conditions. Through strategic DNA testing and sound management, breeders may successfully manage these issues in a way that’s beneficial to the breed and commercial customers.

Genetic Conditions and Genetic Factors

The following abnormalities are considered pathological (disease) conditions of genetic origin. These “genetic conditions” include an impairment of health or a condition of abnormal function due to an abnormal or mutated gene.

The following information includes commonly asked questions, testing guidelines and Association policy for Arthrogryposis Multiplex (AM), Neuropathic Hydrocephalus (NH) and Contractural Arachnodactyly (CA), PRKG2 Gene Mutation for Dwarfism (D2), Myostatin (M1), Oculocutaneous Hypopigmentation (OH) and Osteopetrosis (OS).

Additional information and the complete American Angus Association Genetic Condition Policy is presented in the Breeder’s Reference Guide. Breeders may also contact the Member Services department with questions.
