Retinal dysplasia / Oculoskeletal dysplasia (RD/OSD)

Retinal dysplasia / Oculoskeletal dysplasia (RD/OSD) is a hereditary disease which can be tested with a DNA test. Retinal Dysplasia/Oculoskeletal Dysplasia (RD/OSD) is a hereditary disease present in Labrador retriever breed. Affected dogs have skeletal abnormalities characterized by short-limbed dwarfism and ocular defects including vitreous dysplasia, retinal detachment and cataracts. This phenotype segregates as an autosomal recessive trait. Obligate heterozygotes may exhibit a mild ocular phenotype that ranges from vitreal strands and/or localized retinal dysplasia characterized by focal or multifocal retinal folds, to large plaques of dysplastic retinal tissue, but have a normal appendicular skeleton.

Inheritance: autosomal recessiveread more

Mutation: COL9A3 gene
