Summary:

A recent genetic study provides new information on the occurrence of a DVL2 gene defect associated with a screw tail and its relevance to canine constitution and health. The variant was found in several Bulldog and Pit Bull type breeds, and it was shown to result in caudal vertebral anomalies and shortening of the muzzle. The DLV2 variant may also affect the development of the heart.
