Dear Shari - That is "the link".  The 14% is an average across  three 
geographically dispersed flocks; range being 10%-18%.  When the  lysosomal 
disease was originally discovered, the source was traced to the  original imports 
from Great Britain and the ram bred by Tony Turner (Nova  Scotia), Turner's 
183K.  Knowing the affected lambs and being able to trace  back carriers, 
breeders were told in 2002 (JSC, JSBA, ALBC, USDA) of potential  problems and 
breeders who had Jacobs from the imports through these lines should  be 
aware.  The three flocks tested were breeders who believed they had  stock from 
183K, Lasseau, Fieldwood, etc.  
 
There is good news and bad news: the bad news is they have a mutation  
carrier, the good news is the carrier genetically links their flock to the  
imports and they know which ones are carriers and which are not.  If  you belong 
to a Jacob breed organization, you may want to check with them for  
guidance and any pedigree help.  If I can be of further help, please let me  know.  
Regards, Fred Horak

Fred,
 
I am pasting a link and would like to know if this is the article  that you 
are referring?
Hope this link works as it is very long.  See below:
14% is significant and I had not seen that stat. previously.
Thanks,
Shari Staines
