Regarding CNM and earlier comment about prevalence: The writer might not have seen a case in five years, but we are testing litters regularly that have affected pups in them and/or testing pups that have been placed in homes and the affected symptoms start to show. Remember that carriers do not show symptoms and often breeders do not tell anyone about their affected pups --- so it could be very true that the writer did not see a case in five years.
After I wrote the first version of this post, the person who I was responding to removed theirs. They wrote me personally to sort out what was intended. Therefore my first paragraph above may seem to be a comment out of no-where but I will leave it for now.
Another new comment I want to add is that I have discovered that some people mistake some other diseases with words in them that are somewhat near Centronuclear Myopathy but spelled slightly differently and/or a different kind of myopathy (there are many), but are not CNM. Be careful what you are looking at when you see clearances listed on a web site. There are mistakes on some web sites that mislead people into "maybe" thinking that the dogs are cleared for CNM but it is not the same disease, in some cases.
It is very evident that we have not gotten rid of CNM being carried in pedigrees in the USA or any other of the 18 countries that we deal with regularly.
I know this post does not belong on the EIC sticky list -- but I was not sure where to put it so it would be seen by people reading the comments. Chris should move if he wants to.
If anything, there are more CNM carriers than before since people know how to breed to avoid affected pups in a litter. Carriers show no symptoms so they are not visible to most people. A fair number of people are testing litters with us so they can tell buyers which pups are carriers. Many buyers are quite comfortable buying a carrier ---- as long as they know about it.
There are still many breeders who have no idea about CNM and/or EIC existing. It will be a long time before either are gone from Labradors.
For questions please write me privately at cnminfo@centurytel.net
It was only by sheer chance that I happened to see the post on CNM in the EIC thread as I don't browse very often. And I seldom think to look at my PM folder.
Happy Retrieving
