European Shorthair — Haemophilia A (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: European Shorthair (Cat)Disorder:Mode of inheritance: X-linkedClin feat: Beetz et al. (2024) reported a 3-month-old domestic shorthair tomcat with alternating lameness, fever and inappetence: Coagulation tests revealed an isolated prolonged activated partial thromboplastin time (aPTT). Activity of factor VIII was 5% (reference range: 70–125%), of factor IX 55% (80–130%), and of factor XII 73% (50–140%).Defect: yes

- OMIA molecular-genetics note: Beetz et al. (2024) reported a suspected splice variant in intron 19 of the <em>F8</em> gene (c.6073+2 T>C, omia.variant:1767) as likely causal variant in a 3-month-old domestic shorthair tomcat with haemophilia A.
