Abstract

espanolLa abiotrofia cerebelar (AC) es una enfermedad neurodegenerativa causada por una mutacion en el ADN que afecta a las celulas de Purkinje del cerebelo, produciendo principalmente problemas en el balance y la coordinacion de los animales. Entre las especies que se ven afectadas se encuentra la equina, particularmente la raza Arabe. En este trabajo se presenta el caso de un potrillo arabe que presento sintomatologia compatible con AC. Los hallazgos clinicos se confirmaron mediante estudios moleculares y confirmacion por histopatologia de las lesiones. Los estudios moleculares permitieron confirmar la presencia de la mutacion causal. Dados estos hallazgos y que la sintomatologia neurologica compatible con la abiotrofia cerebelar en equinos no es nueva en nuestro pais, se considera que seria importante estudiar a nivel poblacional la raza Arabe, con el fin de conocer la prevalencia y casuistica de AC en Uruguay. Palabras clave: Abiotrofia cerebelar en equinos, equinos arabe, enfermedad hereditaria. EnglishCerebellar abiotrophy (CA) is a neurodegenerative disease caused by a mutation in the DNA that affects the Purkinje cells of the cerebellum, mainly causing problems in the balance and coordination of animals. Among the species that are affected is equine, mainly the Arabian breed. In this study we presented the case of an Arabian foal with clinic signs compatible with the pathology mentioned before. Histopathological and molecular studies were carried out to confirm the clinical findings, giving results that were positive for CA in both cases. Considering these findings and that the neurological symptomatology compatible with CA in horses is not new in our country, it is important to study the Arabian breed at a population level, in order to know the prevalence of CA in Uruguay.

乌拉圭阿拉伯马小脑非营养的首次分子诊断
西班牙小脑非营养(ca)是一种神经退行性疾病,由影响小脑浦肯野细胞的dna突变引起,主要导致动物平衡和协调问题。受影响的物种包括马,特别是阿拉伯马。在本研究中,我们描述了一种具有与AC一致的症状学的阿拉伯马驹。临床发现通过分子研究和组织病理学证实。分子研究证实了因果突变的存在。由于这些发现,以及与小脑非营养相一致的神经症状在我国并不新鲜,因此认为在人口水平上研究阿拉伯品种是很重要的,以了解ca在乌拉圭的流行和随机化。关键词:马小脑非营养,阿拉伯马,遗传性疾病。EnglishCerebellar abiotrophy (CA)疾病所造成的损害是neurodegenerative mutation in the DNA that affects the Purkinje / of the cerebellum mainly先后problems in the平衡和协调动物。= =地理= =根据美国人口普查,该县的总面积为,其中土地和(3.064平方公里)水。在这项研究中,我们提出了一个阿拉伯小马驹的病例,其临床症状与上述病理一致。组织病理学和分子研究证实了临床结果,给出了两例CA阳性的结果。考虑到这些发现,并且与马体内钙相一致的神经症状在我国并不新鲜,因此必须在人口水平上研究阿拉伯品种,以便了解钙在乌拉圭的流行情况。关键词:马小脑非营养,阿拉伯马,遗传性疾病。
