Caractères / symptômes
|
Maladie dégénérative de la peau (anomalies du collagène): fragilité et élasticité exagérée de la peau, ainsi que troubles de la cicatrisation des plaies. Âge: >1.5 an (lié à l’utilisation). D’autres tissus riches en collagène (tendons, ligaments, gros vaisseaux sanguins) peuvent aussi être touchés (Bowser JE et al 2014).
La maladie n’est pas curable.
L'hyper-élasticité et la fragilité de la peau sont des symptômes cardianux du syndrome de Ehlers-Danlos, un groupe hétérogène d’affections génétiques du tissu conjonctif (voir le syndrome d'Ehlers-Danlos chez l’homme). HERDA et le Syndrome du poulain de sang fragile appartiennent à ce groupe. Des cas indépendants de la mutation PPIB ont été décrits (Rüfenacht S et al 2010; Steelman SM et al 2014). On peut s’attendre à ce que d’autres mutations causales soient identifiées à l’avenir.
|
Contraintes |
Restriction sévère héréditaire d'une fonction organique (peau); hyperélasticité de la peau; risque accru de blessures (surtout l’emplacement de la selle, le dos, les membres), hématomes, les blessures se cicatrisent mal, le cheval ne peut plus être utilisé (selle, voiture): dommages qui provoquent des pertes de fonctionnalité affectant l’état général. Les critères déterminants pour l’évaluation des contraintes sont en particulier:
Stratégie d’élevage et mesures
Parents
Recherche ADN de la mutation causale (Tryon RC et al 2007); accouplements ciblés, adaptation de la stratégie d’élevage (les animaux porteurs ne devraient pas être affectés à l’élevage) Descendants atteints
Diagnostic (examen ADN); les animaux atteints ne doivent pas être affectés à l’élevage; euthanasie |
Races
|
Quarter horse (QH), lignées de cutting, paint horse, appaloosa, races apparentées
|
% de porteurs | QH 3.5% (Badial PR et al 2013a: 5.8%), Elite cutting: 28.3% (Tryon RC, 2005, cit. Lenz 2010) |
Fondateur | Poco Bueno |

|
Remarques
|
Une pathologie analogue (Rüfenacht S et al, 2010) peut être observée dans d’autres races (p. ex. cheval de sport CH, pur-sang anglais). Voir aussi les autres maladies héréditaires de la peau (Syndrome du poulain de sang fragile, Épidermolyse bulleuse jonctionnelle (EBJ1), Épidermolyse bulleuse jonctionnelle (EBJ2)).
