You then corrected yourself to this:
Right now, any and ALL folds will fail a pup and they will not get a CERF number. There is one type of folds that are associated with dwarfism. There are also a couple other types of folds that are not.
I have not differentiated on this thread about focal or geographic folds. You posted this after I disagreed with your original statement.
1) 99 % of folds found in Labs are GEOGRAPHICAL folds. 2) The optigen test is for focal folds. 3) If your dog has folds they will NOT get a CERF number.**** This has been changed in the last year. Here is the quote fromOptigen's site".CERF Certification for Labradors or Samoyeds with Retinal Folds: The breeding advice for Labrador Retrievers and Samoyeds diagnosed with "retinal dysplasia - folds" will be changed from "No" to "Breeder option" if the owner of the dog provides the CERF office with results of the DNA test for the affected dog, showing that it is not a carrier of the oculoskeletal dysplasia (OSD) mutation" Please note that these comments refer only to Focal/Multi-focal reitnal dysplasia (retinal folds). Geographic retinal dysplasia may represent a different, possibly inherited, disease. 4)There are "other" types of folds that are inherited that are not focal folds.
