Though the exact frequency in the overall golden retriever population is unknown, approximately 44% out of 1600 golden retrievers tested from Australia, France, Switzerland, and the United States were carriers of the mutation and approximately 29% were affected. -. Milder forms are manageable with baths and mineral oil. PMC CAS Scale as a clinical sign in puppies may be associated with myriad causes including nutrition, allergies, parasites and infection. Genetic testing of the PNPLA1 gene in golden retrievers will reliably determine whether a dog is a geneticCarrier of Ichthyosis (golden retriever type). Weight loss and lethargy are associated with ICH-2. It causes flaking of the skin, because the outermost layer of skin does not develop normally. Schweiger, M. et al.

In general, carrier dogs do not have features of the disease but when bred with another carrier of the sameMutation, there is a risk of having affected pups. Ichthyosis (golden retriever type) is inherited in an Autosomal Recessive manner in dogs meaning that they must receive two copies of the mutated gene (one from each parent) to develop the disease. Tan, E.K., Ho, P., Tan, L., Prakash, K.M. A skin biopsy is needed to definitely diagnose the condition, as it can be difficult to distinguish ichthyosis from many other skin diseases. Objectives: Science 267, 525528 (1995). Each pup that is born to this pairing has a 25% chance of inheriting the disease and a 50% chance of inheriting one copy and being a carrier of the PNPLA1 gene mutation. 34, 35 ). Genet. C.D.
