Test Overview:

Do not breed two carriers (C/T x C/T)—as this carries a 25% risk of affected puppies (T/T), 50% carriers, and 25% clear. Ideal: Breed clear dogs (C/C) to clears or carriers (C/T)—no affected offspring, but carriers may persist. Do not breed affected dogs (T/T). Long-term strategy: Gradually reduce carrier frequency while retaining genetic diversity.

Category:

Musculoskeletal - Associated with muscles, bones and associated structures

Gene:

Integrin subunit alpha 10 (ITGA10) on Chromosome 17

Variant Detected:

chr17:58703935 (canFam3): C>T

Severity:

Moderate. This disease can cause significant signs of discomfort and/or dysfunction in affected animals. It may involve relatively high treatment/management costs, and can sometimes reduce life expectancy.

Mode of Inheritance:

Autosomal Recessive
