12. A method for detecting a mutated canine von Willebrand Factor gene in a canine DNA sample comprising the steps of:
-
a) amplifying the DNA sample by polymerase chain reaction to produce polymerase chain reaction products, wherein the polymerase chain reaction uses primers that produce a restriction site in a mutant allele but not in a normal allele, wherein the mutation in the mutant allele is a base deletion at nucleotide 937 of the gene encoding canine von Willebrand Factor (SEQ ID NO.
1);
b) digesting the polymerase chain reaction products with a restriction enzyme specific to the restriction site of the restriction site primer to produce DNA fragments; and
c) detecting the DNA fragments, thereby detecting a mutated canine von Willebrand Factor gene. - View Dependent Claims (13, 14, 15)
