Genetic Test Codes

The genetic condition status of Australian Angus animals is routinely displayed for the following genetic conditions:

  • Arthrogryposis Multiplex (AM)
  • Contractual Arachnodactyly (CA)
  • Neuropathic Hydrocephalus (NH)
  • Red gene (RD)
  • Mannosidosis (MA)
  • Developmental Duplications (DD)

An animal’s genetic condition status is based on DNA samples provided by breeders.

Description of the Genetic Test Codes

AMF

CAF

NHF

RDF

MAF

 DDF

Indicates that the sample submitted for this animal has been tested and found to be free of the causative mutation responsible for the genetic condition (AM, CA, NH, RD, MA or DD). This animal is homozygous free, meaning that it has two copies of the normal variant (or allele) of the gene.

AMC

CAC

NHC

RDC

MAC

DDC

Indicates that the sample submitted for this animal has been tested and found to be a carrier of the causative mutation responsible for the genetic condition (AM, CA, NH, RD, MA or DD). This animal is heterozygous for the mutation, meaning that it has one mutant allele and one normal allele. This animal could pass the  mutation to approximately half of its progeny.

AM_%

CA_%

NH_%

DD_%

Indicates that, based on pedigree information supplied by the breeder of the animal, the animal has a chance to be a carrier of the mutation responsible for the genetic condition (AM, CA, NH or DD) but has not been tested. The higher the indicated percentage, the larger the chance the animal may be a carrier. To verify the status of this animal, Angus Australia recommends that  testing be undertaken prior to using this animal for breeding  purposes.

AMFU

CAFU

NHFU

DDFU

Indicates that, based on pedigree information supplied by the breeder of the animal, the animal is expected to be free of the mutation responsible for the genetic condition (AM, CA, NH or DD) but has not been tested. This animal has not been tested for the causative mutation and Angus Australia gives no guarantee as to the animal’s “free” status.

AMA

CAA

NHA

DDA

Indicates that the sample submitted for this animal has been tested and the animal found to be homozygous for the mutation responsible for the genetic condition (AM, CA, NH or DD) and have two copies of the mutant variant of the gene.
Note, for some recessive conditions such as DD, not all homozygous animals appear to display phenotypic expression of the condition.
