Osteochondrodysplasia (OCD) in Miniature Poodles

Quick Summary

Osteochondrodysplasia is characterized by stunted growth and abnormal locomotion. Affected animals develop splayed hind limbs, enlarged joints, flattened rib cages, shortened and bent long bones, and deformed paws.

Phenotype: Osteochondrodysplasia is characterized by stunted growth and abnormal locomotion. Affected animals develop splayed hind limbs, enlarged joints, flattened rib cages, shortened and bent long bones, and deformed paws.

Mode of Inheritance: Autosomal recessive

Alleles: N = Normal, OCD = Osteochondrodysplasia

Breeds appropriate for testing: Miniature Poodle

Explanation of Results:

  • Dogs with N/N genotype will not have osteochondrodysplasia and cannot transmit this osteochondrodysplasia variant to their offspring.
  • Dogs with N/OCD genotype will not have osteochondrodysplasia, but are carriers. They may transmit this osteochondrodysplasia variant to 50% of their offspring. Matings between two carriers are predicted to produce 25% osteochondrodysplasia-affected puppies.
  • Dogs with OCD/OCD genotype will have osteochondrodysplasia, an inherited skeletal and cartilaginous disorder.

Price

$50 single test per animal ($5 discount on 3 or more dogs)
$30 as additional test on same animal

Turnaround Time
At least 15 business days; may be delayed beyond 15 business days if sample requires additional testing, or a new sample is requested.
Additional Details

Osteochondrodysplasia (OCD) is an inherited disorder found in Miniature Poodles. The disease is characterized by stunted growth and abnormal locomotion that can be observed at about 3 weeks of age. Affected animals develop abducted (splayed) hind limbs, enlarged joints, flattened rib cages, shortened and bent long bones and deformed paws. The inheritance is autosomal recessive, thus both sexes are equally affected and carriers show no signs of the disease. Research has identified a deletion in the Sulfate Transporter gene, SLC13A1, which is associated with OCD in Miniature Poodles.
