Cornell scientists identify rare human genetic disorder in two unusually long-legged cats
Cornell University researchers have identified the first documented cases of Marfan syndrome in domestic cats. By analyzing the DNA of two long-legged brothers, scientists discovered mutations in the FBN1 gene that mirror the human condition.
Why it matters
This discovery provides a new animal model for studying Marfan syndrome, which could lead to improved veterinary diagnostics and better understanding of the genetic disorder in humans.
Two brothers named Gary and Shaggy have helped Cornell University researchers make a rare genetic discovery. In a study published in Scientific Reports , scientists reported the first molecular characterization of Marfan syndrome in domestic cats, a condition primarily recognized in humans.
Gary and Shaggy first stood out as kittens because of their unusually long limbs. As they grew older, veterinarians also identified abnormalities in their eye structures and an enlarged aorta, the body's main artery. Together, these symptoms suggested Marfan syndrome, an inherited condition that weakens connective tissues throughout the body. The disorder affects approximately 1 in 4,000 people, but these brothers represented the first known documented feline cases.
