Italian greyhounds are an ancient breed, developed in Italy to be companions and a lap dog for women in the Middle ages, however also had endurance, speed and a desire to hunt small game. These days it is a household pet who excels in many sports and conformation.

Italian greyhound breeders have expressed that autoimmune disorders are their largest concern. Autoimmune illnesses reported include (but are not limited to) Addison's disease, IMTP, AIHA, and MMM. Also of concern are epilepsy and leg breaks due to low bone density.
Italian Greyhounds from the United States and European countries were tested at UC Davis. Genetic analysis showed that American and European both had breed specific genetic clusters, but with very different genetics. It was found that being homozygous increased risk for autoimmune disease.
The breed appears to have reasonable breed-wide diversity, but this diversity is very unbalanced. The average number of alleles in the breed is 7, however the effective alleles only 3.39. This indicates a need to redistribute alleles breedwide and presence of a bottleneck.
Italian Greyhounds from the United States and European countries were tested at UC Davis. Genetic analysis showed that American and European both had breed specific genetic clusters, but with very different genetics. It was found that being homozygous increased risk for autoimmune disease.
18 different STR-associated DLA Class I and 17 DLA Class II haplotypes have been identified to date in Italian Greyhounds. This is fairly average for a purebred population.
The follow includes dogs with birthdates listed in the database.
DLA Haplotypes in the Breed
The Dog Leukocyte Antigen or DLA is the region in the canine genome that controls the immune system, among other things. There are three classes or areas, and the VGL Canine Diversity Test genotypes or records the two regions with the most variation. Because it is an area that mutates more rapidly than others, the method VGL uses is ideal for identifying specific combinations of DNA, and not merely showing whether a dog inherited two of the same sets of genetics from its parents or two different ones.
"Haplotype" is a generic name for a set of genes that are bound together and inherited as a set. The DLA Class I and Class II haplotypes are very tightly bound and represent about 2 million base pairs of DNA - a sizeable chunk. These two haplotypes together make an extended haplotype that is nearly always passed from parent to puppies as a pair. We therefore have two tables below showing both the combinations of DLA found in this breed and how often they appear, and also how often they appear individually.
Remember that frequency percentages do not show how many dogs carry them, but rather how many of these haplotypes exist in the breed as a whole. Every dog has two sets of DLA haplotypes, one inherited from dam, and one inherited from sire. These almost never recombine in new generations.
