Cornell scientists identify rare human genetic disorder in two unusually long-legged cats
Reported by ScienceDaily · October 14 at 1:56 PM · Summary by Pawdeck
Cornell University researchers have reported the first genetically confirmed cases of Marfan syndrome in domestic cats, based on two brothers named Gary and Shaggy. Both cats had unusually long limbs, eye abnormalities and an enlarged aorta, and genetic testing found two altered copies of the FBN1 gene.
Background
Marfan syndrome is an inherited condition that weakens connective tissue, which supports structures such as blood vessels, bones, ligaments, skin and eyes. In humans it is usually caused by a change in one copy of the FBN1 gene, and it can affect the heart and eyes over time.
Why it matters
It shows that a connective tissue disorder long known in people may also occur in cats, which could help vets recognize similar cases.
What you can do
If your cat has unusually long limbs or any unexplained eye or heart changes, mention them to your veterinarian at the next visit. Genetic testing for this condition is not yet widely available.
