DLA haplotype are three times more likely to develop diabetes than dogs with other haplotypes.

The graph shows the number of
haplotypes found in a survey of each breed, separated into Class I and Class II
DLA.
We demonstrated significant differences in dog leukocyte antigen (
DLA)
haplotype frequencies in six of these breeds: Cocker spaniel, Springer spaniel, Labrador, West Highland white terrier (WHWT), Bearded collie, and Standard poodle.
In the Springer spaniel, the
DLA - DRB1 * 015:01 — DQA1 * 006:01 — DQB1 * 023:01
haplotype was significantly associated with disease risk (p = 0.014, odds ratio (OR) = 5.14) and showed a similar trend in the Cocker spaniel.
Similar
haplotypes shared between breeds were demonstrated, with
DLA - DRB1 * 001:01 — DQA1 * 001:01 — DQB1 * 002:01 more prevalent in both affected Labrador (p = 0.0002, OR = 3.06) and WHWT (p = 0.01, OR = 2.11).
Preliminary sequence analysis of the dog leukocyte antigen (
DLA) gene in a heterogeneous population of canine diabetics revealed that one
haplotype is overrepresented (84,89).
Association of hypothyroid disease in Doberman Pinscher dogs with a rare major histocompatibility complex
DLA class II
haplotype.
Forty one percent of the breed shared a single
DLA class I and 62 % a single class II
haplotype.
The same was true for
DLA class I and II
haplotypes.
The diversity of
DLA class I and II
haplotypes was low, with only 11 identified
DLA class I and nine class II
haplotypes.
Nineteen percent of the dogs were homozygous for the dominant
DLA class I
haplotype and 42 % for the dominant
DLA class II
haplotype.
Although the
DLA region is only a small part of the genome, the importance of these
haplotype imbalances, small
haplotype numbers, and increased homozygosity should not be underestimated [23, 42].
The nine
DLA class II
haplotypes recognized in this group of English bull dogs were only a fraction of the 88
haplotypes that were reported for dogs in 2007 [51].
Thirty - three STR loci across 25 chromosomes were used to assess genomic diversity, while four STR loci were used to determine
DLA class I
haplotypes and three STR loci were used for
DLA class II
haplotypes.
The low number of different
DLA class I and II
haplotypes in English bulldogs was associated with an imbalance in the relative frequency of each
haplotype.
