This disease is caused by a mutation in the calcium activated neutral proteinase 1 (CAPN1)-gene. Affected dogs will show first indications of the ataxia at the age of 6-12 months. First clinical signs are loss of balance and minor incoordination of gait while later symptoms can be a progressive incoordination or a complete loss of mobility.

Breeds: Jack Russell Terrier, Parson Russell Terrier

Trait of inheritance: autosomal-recessive


The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing Procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer. Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.

Test duration: 3-5 days after arrival of the sample in the lab
