Although there isn't a genetic marker for LS at present, there are some very good tests that can be done that are good indicators of carriers. Dr. Center, who is currently working on finding the marker, says that no Yorkie with a bile acid test higher than 15.00 should be used in a breeding program. This would be a good start to weeding some of the carriers out.
Hopefully, the genetic marker will be found this year and everyone breeding Yorkies will take advantage of it.
