Harrier — Hypocatalasia (hereditary; OMIA-verified breed predisposition)

Source: first-hand OMIA (University of Sydney) breed-specific hereditary-disorder record, saved verbatim to source_file; every claim below is a C1 byte-substring of it.

Claims

  • Breed: Harrier (Dog)
  • Disorder:
  • Mode of inheritance: Autosomal
  • `Clin feat: Catalase is an enzyme responsible for breaking down reactive oxygen species. As there are other enzymes able to fulfil this role, hypocatalasia often has no clinical signs. Hypocatalasia has been associated with ulcers of the oral cavity leading to gangrene, a condition known as “Takahara disease” in humans (Fukuda et al., 1982). The pathogenesis of this disease is explained by some oral bacteria producing hydrogen peroxide, which is unable to be decomposed due to catalase deficiency (Ogata et al. 2008). leading to the substitution of alanine(327) (GCT) by threonine (ACT)".
