Plain-English summary
A family of St. Bernards had four puppies that were born with several serious birth defects, including missing ears (anotia), a cleft palate (palate agenesis), a split tongue (bifid tongue), extra toes on their back paws (polydactyly), and additional vertebrae and ribs. These issues are likely caused by a genetic syndrome passed down from their parents. Unfortunately, the puppies' conditions are quite severe, and the long-term outcomes for such genetic issues can be challenging. Pet owners should be aware of these potential genetic problems when breeding dogs.

Abstract
A presumed genetic syndrome is described in a family of St. Bernards. Four identically affected littermates presented the association of palate agenesis, anotia, incomplete bifid tongue, preaxial hind paw polydactyly, and an extra thoracic vertebra and rib. Pedigree analysis is compatible with an autosomal recessive gene.
