Abstract

Background: To report the occurrence of choroidal hypoplasia in the Australian Kelpie breed in Poland, the affected dogs testing positive for the Collie Eye Anomaly NHEJ1 gene mutation. Case presentations: Choroidal hypoplasia (CH) was initially diagnosed in a young female Australian Kelpie...

Abstract

Collie eye anomaly (CEA) is a hereditary, congenital eye disease mainly affecting Collies but also occurs in other breeds. The genetic background is unclear. Chorioretinal dysplasia (CRD) and coloboma are the two primary changes in CEA. Colobomas and secondary lesions can give rise to visual...

Abstract

In light of improving breeding advice, the frequency was estimated for all the disease-causing mutations that were known at the start of the study and that are potentially relevant for a group of dog breeds, which are relatively popular or in which the genetic diversity in Belgium is low to...

Abstract

The aim of this study was to investigate the existence of parallel and simultaneous selection for the collie eye anomaly (CEA) and the ivermectin toxicosis MDR1 gene mutation in different dog breeds in Japan. 1331 DNA samples were collected from Collies, Border Collies, Salukis, Toy Poodles,...

Abstract

Objective: To describe the frequency of the nonhomologous end-joining factor 1 (NHEJ1) mutation and the compliance between clinical and genetic diagnosis of choroidal hypoplasia (CH) in a group of Norwegian Border Collies. Animals studied: Border collie puppies in the age from 5 to 8 weeks....

AbstractFull Text

Collie eye anomaly (CEA) is an inherited congenital visual impairment with heterogeneous signs. The first symptoms are already visible in the early embryo. Among the most affected breeds are Collies and Shetland Sheepdogs but the disease has spread to different breeds depending on the country of...

Abstract

Collie eye anomaly (CEA) encompasses a spectrum of different ophthalmic phenotypes from clinically inconsequential choroidal hypoplasia to blindness from coloboma of the optic nerve head (ONH). A previous study found a 7.8-kb deletion in intron 4 of the NHEJ1 gene to be associated with CEA. A...

AbstractFull Text

Canine genetic disorders inherited through genes or chromosomes. Mutations can also occur spontaneously or influenced by environmental factors. Such disorders can be transmitted to offspring. However, the disease may not be developed owing to other influenced factors. Dominant and recessive genetic ...

Abstract

In this retrospective study, the results of 3'527 eye examinations in 6 different breeds affected with Collie Eye Anomaly (CEA) over a period of 8 years (1999-2007) are described. CEA was divided into three main ophthalmoscopic features, (a) choroidal hypoplasia (CRH), (b) CRH and coloboma and (c)...
