Labrador Tricuspid Valve DNA Study

North Carolina State University is looking for DNA samples from Labrador Retrievers for a genetic study that evaluates unique DNA changes that may be associated with the congenital heart disease, tricuspid valve dysplasia.

At this time, we would like to collect DNA samples from 100 Labrador Retrievers. We need DNA from both healthy Labrador Retrievers without heart disease and from Labradors with tricuspid valve dysplasia.

Ideally, the DNA would be from a wide number of families so we are hoping to get samples from as many different families as possible.

Thank you for your help!

Dr. Kate Meurs, North Carolina State University
