  2. Progressive retinal atrophy - Wikipedia

    en.wikipedia.org/wiki/Progressive_retinal_atrophy

    Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.

  3. Cerebellar abiotrophy - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_abiotrophy

    Symptoms of cerebellar abiotrophy include ataxia or lack of balance, an awkward wide-legged stance, a head tremor (intention tremor) (in dogs, body tremors also occur), hyperreactivity, lack of menace reflex, stiff or high-stepping gait, coarse or jerky head bob when in motion (or, in very young animals, when attempting to nurse), apparent lack ...

  4. Canine degenerative myelopathy - Wikipedia

    en.wikipedia.org/wiki/Canine_degenerative_myelopathy

    A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).

  5. Collie eye anomaly - Wikipedia

    en.wikipedia.org/wiki/Collie_eye_anomaly

    Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs, which affects the retina, choroid, and sclera. It can be a mild disease or cause blindness. CEA is caused by a simple autosomal recessive gene defect. There is no treatment.

  6. List of genetic disorders - Wikipedia

    en.wikipedia.org/wiki/List_of_genetic_disorders

    The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.

  7. Labrador Retriever coat colour genetics - Wikipedia

    en.wikipedia.org/wiki/Labrador_Retriever_coat...

    The gene affecting this colour variation in all dog breeds is the recessive 'dilution' (D) locus. It is possible for each of the standard colour genotypes to be diluted if the dog carries two copies of the recessive dilute allele, dd. Dogs that carry at least one D will not have a diluted coat.

  8. GM1 gangliosidoses - Wikipedia

    en.wikipedia.org/wiki/GM1_gangliosidoses

    The GM1 gangliosidoses, usually shortened to GM1, are gangliosidoses caused by mutation in the GLB1 gene resulting in a deficiency of beta-galactosidase.The deficiency causes abnormal storage of acidic lipid materials in cells of the central and peripheral nervous systems, but particularly in the nerve cells, resulting in progressive neurodegeneration.

  9. Dilution gene - Wikipedia

    en.wikipedia.org/wiki/Dilution_gene

    The dilute gene d is recessive to the wild type allele D. A gene test can be used to determine a dog's genotype concerning genes for pigmentation. In some dog breeds lightened by the dilute gene, the mutation d is associated with color dilution alopecia (CDA). Since not all breeds in which the gene occurs exhibit these problems, it is suspected ...
