Two genetic variants have been associated with congenital ichthyosis in the Golden Retriever. Careers. We subsequently found one missense and one nonsense mutation in the catalytic domain of human PNPLA1 in six individuals with ARCI from two families. Milder forms are manageable with baths and mineral oil. PMC Akiyama, M. & Shimizu, H. An update on molecular aspects of the non-syndromic ichthyoses. The condition often progresses to large patches of thickened, black, scaly skin. PNPLA 1 mutations cause autosomal recessive congenital ichthyosis in John Wiley & Sons Ltd, 2013. Homozygous Affecteds (2-2) are expected to develop signs consistent with Ichthyosis (ICH-2) and all of their offspring will inherit a disease variant allele. Cadiergues, M.C. There may be other causes of this condition in dogs and a normal result does not exclude a different mutation in this gene or any other gene that may result in a similar genetic disease or trait.

MeSH Autosomal recessive congenital ichthyosis (ARCI) in golden retrievers is due to a PNPLA1 gene mutation, which plays a role in epidermal lipid organization and metabolism. Autosomal recessive congenital ichthyosis due to PNPLA1 mutation in a golden retriever-poodle cross-bred dog and the effect of topical therapy. Examinations were performed prior to and at 14 and 30 days of treatment to assess scaling, presence of other skin lesions and pruritus.
