A deletion mutation causes hemophilia B in Lhasa Apso dogs.

Hemophilia B is a bleeding disorder caused by a deficiency of clotting factor IX (FIX). A colony of FIX deficient Lhasa Apso dogs has been established and the molecular basis of hemophilia B has been determined. The plasma factor IX levels were < 1% of normal canine levels in affected dogs. A complex deletion mutation at nucleotides 772-777 was found when hepatocyte cDNA from a hemophilia B dog...
