FAB/PKD results

 

  
 

 

The following are the results of cats scanned under the FAB screening scheme and through the gene test to April 2009.

In all breeds except Persians,Exotics and British Shorthairs the numbers scanned are too low to provide reliable statistics.

The figures shown here are since the scheme began but they hide the most exciting part of the story.  When screening began in 2001, 40% of Persions and 35% of Exotics tested positive.  In 2006 and 2007 the Persian score stood at 22-23% and in 2008 it was 14% positive.  Exotics fell to 10-12% in 2006 and 2007 and of the four tested in 2008 none were positive (see other tables).

There has always been a concern that some British Shorthairs may be affected as Persians had been used in the breeding occasionally.  In 2007, 37 British Shorthairs were tested and two were positive.  In 2008 a further 53 were tested and one found to be positive.  Currently many more are being tested to try and eliminate PKD from the breed.

The fact that no PKD-positive cats are listed under some breeds does not mean that these breeds are clear of PKD - some cats of various breeds scanned positive for PKD before the scheme was introduced.

Other Breeds:

Cat breeds which have been developed using Persian bloodlines and breeds that have allowed out-crossing to Persian cats may also have a proportion of affected cats.

*In other unrelated breeds, PKD is a rare condition. Cysts in the kidneys can occur for reasons other than autosomal dominant PKD which is seen in Persians.
