Paw Print Genetics, a new genetic testing laboratory dedicated to canines, seeks cheek swab samples from English Springer Spaniels that are affected or carriers for either PFK (phosphofructokinase deficiency) or fucosidosis to assist in validating their DNA testing protocols.  If you can offer assistance with this process please contact Martine Huslig at Paw Print Genetics, 509.483.5950 or mhuslig[at]pawprintgenetics.com.
