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.
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.
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).
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.
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.
A young leukemia patient recently received a special visit from two therapy dogs, and the sweet encounter was shared in an Instagram reel that has gone viral with nearly 10 million views. In ...
Heart failure has historically been irreversible, but a new study suggests that could change. At the University of Utah, scientists used a new gene therapy that reversed heart failure in animals.
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 ...
