Breeds Affected: American Staffordshire Terrier, Australian Shepherd,  Black Russian Terrier, Boerboel, Bulldog, Dalmation, Danish-Swedish Farm dog, German Hunting Terrier, German Shepherd Dog, Giant Schnauzer, Kromfohrländer, Labrador Retriever, Lagotto Romagnolo, Large Munsterlander, Parson (Jack) Russell Terrier, Pomeranian, Spaniel de Pont-Audemer, Swedish Vallhund, Weimaraner

Samples Accepted: Blood, Buccal Swabs

Disease Information: Dogs with Hyperuricosuria and Hyperuricemia (HUU) excrete uric acid in the urine, resulting in urolithiasis, the formation of calculi (stones) in the urinary tract.

Inheritance Information: HUU is autosomal recessive, meaning that animals with two copies of this allele will be affected. Animals with one copy of the gene will be clinically-normal carriers.

The possible genotypes are:
N/N The dog is normal, and cannot produce affected offspring.
N/huu The dog is a carrier, and can pass the allele on to approximately 50% of any offspring. If bred to another N/huu carrier, approximately 25% of the offspring will be normal, 50% will be carriers, and 25% will be affected.
huu/huu The dog is affected. If bred to a normal animal, 100% of the offspring will be carriers. If bred to an N/huu carrier, 50% of the offspring will be carriers and 50% will be affected.

– Carriers may be bred to normal animals (N/huu x N/N) without any risk of producing affected offspring. The offspring should be tested before breeding to determine if they are carriers or normal.
– Breeding two carriers (N/huu x N/huu) is not recommended due to the possibility of 25% of the offspring being affected.
– Affected animals (huu/huu) should not be used for breeding.

Test Information: This mutation test identifies a single base change in the SLC2A9 gene.  All Dalmatians are homozygous for this trait (affected).
