Affected animals (those with two copies of the recessive allele) are stillborn due to underdeveloped lungs (Pulmonary Hypoplasia) and swelling caused by excessive fluid retention (Anasarca). Associated dystocia can also lead to death of the cow. There are two causal variants for the PHA condition. One is referenced as the Shorthorn variant (PHA) and the other as the Dexter variant (PHAD). Samples submitted are tested for both variants, regardless of breed.

Additional Information

  • Variant 1 = Shorthorn Variant:
    • PF - Free
    • PC - Carrier
    • PA - Affected
  • Variant 2 = Dexter Variant:
    • PFD - Free
    • PFDC - Carrier

Results will come back as a combination of these variants. For example, an animal that is PF/PFD is free for both the Shorthorn and Dexter variant of the gene.
