Hypocatalasia (Acatalasemia)

Breeds

Relevance Rating: Unknown, not evaluated or no evidence for test for these breeds

General

Disease Name
Hypocatalasia (Acatalasemia)
Gene Name 2
SLC2A9
Mutation
c.979G>A
Mutation 2
c.979G>A
Test Type
Genetic Disease/Disorder
Details
Hypocatalasia is considered to be a rare genetic disorder. Symptoms have been poorly described or are missing from the literature. It is suspected that affected dogs have a higher risk of developing open sores (ulcers) inside the mouth that may lead to gangrene of the mouth. Affected dogs most commonly show no or few signs, and the disorder is usually diagnosed when checking other symptoms.
Details 2
Hypocatalasia is a genetic disorder characterized by impaired catalase activity in the erythrocytes. Symptoms have been poorly described or are missing from the literature. It is suspected that affected dogs have a higher risk of developing open sores (ulcers) inside the mouth that may lead to gangrene. Affected dogs are most commonly asymptomatic and the disorder is usually diagnosed when checking other symptoms. When the symptoms are present, they usually include oral gangrene and ulcer. Generally considered to be rare.
