English Cocker Spaniel — Xanthine urolithiasis; xanthine nephrolithiasis (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: English Cocker Spaniel (Dog)
  • Disorder: Xanthine urolithiasis; xanthine nephrolithiasis
  • Mode of inheritance: Autosomal recessive
  • `Clin feat: In affected dogs with MOCOS deficiency excess xanthine builds up in the urine, a product which has a low solubility and readily precipitates out of urine, creating xanthine calculi (Furrow et al., 2016). These calculi act similar to most uroliths, creating partial or complete urethral obstruction, resulting in intermittent or consistent stranguria and dysuria, and may result in secondary renal damage (Furrow et al., 2016). In the dogs investigated by Tate et al. (2021) age at first diagnosis ranged from 7 weeks to 4 years. C R Acad Hebd Seances Acad Sci D — PubMed:PMID4982510 — OMIA Phene_Article / Article
