Devon Rex and Sphynx “Spasticity”

A recessive mutation that causes a congenital muscle weakness, “myopathy” in Devon rex and Sphynx cats has been discovered by a world-wide research team of geneticists and neurologists from the University of Missouri, the University of California – Davis, the University of California -San Diego, the University of Sydney and the University of Milan. The mutation affects a gene, COLQ, which causes a congenital myasthenic syndrome (CMS) that is similar to humans.

Affected cats present with passive ventroflexion of the head and neck, head bobbing, scapulae protrusion, megaesopahagus, generalized muscle weakness and fatigability. The disease likely started in Devon Rex and spread to Sphynx. Cats show prominent lordosis and generally succumb to the disease by asphyxiation due to choking on food or aspiration pneumonia by two years of age. Signs became evident at three to 23 weeks of age and then usually progressed slowly or remained static. Cats must have 2 copies of the mutation to have disease.

Moderately to severely affected cats show evidence of more generalized muscle weakness, particularly following exertion, stress or excitement. Typically they have a high-stepping forelimb gait, head bobbing and progressive dorsal protrusion of the scapulae. Affected cats tire easily with exercise, with progressive shortening of the stride and superimposed tremor. Eventually they collapse in sternal recumbency, typically with the head coming to rest on, or to one side of, their front paws. Affected cats frequently adopt a characteristic ‘dog-begging’ or “chipmunk” position, usually with their front legs resting on a convenient object.

The disease was first described in the UK in 1989 with detailed presentations from Australia in 1993. Cats have been identified in the USA and more recently across Europe.

Van Antagene kreeg ik vandaag onderstaande mail:

Les recherches menées par le Dr Marie Abitbol (ENVA) en collaboration avec l'équipe du Dr Stéphane Blot (service de Neurobiologie ENVA) et ANTAGENE ont permis d'identifier la mutation responsable de la spasticité, également appelée myopathie, chez le Devon Rex et le Sphynx.

Cette maladie grave s'exprime avant 5 mois par une faiblesse musculaire, une fatigue importante, des difficultés locomotrices, une saillie des omoplates et port de tête bas avec le cou incurvé vers le bas.

Le développement du test génétique est en cours, nous serons en mesure de vous le proposer dès début juillet. Vous pouvez déjà le pré-commander en remplissant le formulaire de pré-commande

Le LOOF a attribué un financement au Dr Marie Abitbol pour mener ce programme de recherche.

Hieronder de vertaling van Google Translate:

Onderzoek uitgevoerd door Dr. Marie Abitbol (ENVA) in samenwerking met het team van Dr. Stéphane Blot (dienst Neurobiologie ENVA) en Antagene hebben de mutatie geïdentificeerd die verantwoordelijk zijn voor spasticiteit, ook wel myopathie, met Devon Rex en de Sphynx.

Deze ernstige ziekte wordt uitgedrukt eerste vijf maanden van spierzwakte, ernstige vermoeidheid, motorische problemen, uitstekende schouderbladen en lage hoofd wagen met gebogen nek naar beneden.

De ontwikkeling van genetische tests aan de gang is, zullen we in staat zijn om u begin juli te bieden. U kunt nu al pre-order door het invullen van de pre-order formulier

LOOF gehonoreerd Dr. Marie Abitbol om dit onderzoeksprogramma uit te voeren
