Claims
Breed: Dachshund, Miniature Wire-Haired (Dog)Disorder:Mode of inheritance: Autosomal recessiveSummary: Mischke et al. (2021): “we present a family of miniature wire-haired Dachshunds segregating for congenital afibrinogenemia. We employed homozygosity mapping, a genome-wide association study (GWAS), and sequencing of fibrinogen genes in order to identify a mutation responsible for afibrinogenemia.”Clin feat: Mischke et al. (2021): “Three seven-week-old miniature wire-haired Dachshunds were presented … with excessive bleedings after fitting with a chip two days before. Two puppies were female and one male. One female died a few days later due to severe bleedings. The second female puppy survived up to an age of one year. Owners reported recurrent episodes with severe bleedings in the skin and gums. The third affected male puppy is under intensive veterinary care and still alive at the age of seven years despite intermittent severe bleeding episodes. … Case 4 … died from a hemoabdomen after a traumatic splenic rupture.Defect: yesPathology: Mischke et al. (2021): In the affected dogs, PT [Prothrombin time](standard test), aPTT [activated partial thromboplastin time], and TT [thrombin time assay] exceeded the upper limits of detection (200 s). PT measured with the optimized assay revealed increased or normal activities of factors II, V, VII, and X, respectively (case 1: 149%; case 2: 104%; case 3: 126%; 100% = average of normal adult dogs) and a moderate reduction in case 4 (44%, reference range in adult dogs: 75–130%). Fibrinogen concentration according to the coagulometric Clauss method was below the lowest detection limit in all four cases (0.2 g/L; reference 1.0–3.0 g/L). Platelet count was normal in all four affected animals suffering from bleeding complications.”
