Study finds treatment for blindness causing syndrome
Researchers have found a promising way to develop gene and cell therapies, capable of treating blindness-causing syndrome.
A genetic mutation that leads to a rare, but devastating blindness-causing syndrome has been discovered in monkeys for the first time. The findings offers a promising way to develop gene and cell therapies that could treat the condition in people.
Three species of monkeys ( rhesus macaques) with a mutated gene that's associated with Bardet-Biedl Syndrome have been discovered, according to a study published in the journal.
It is the first known naturally occurring nonhuman primate model of the syndrome, which is also called BBS.
BBS leads to vision loss, kidney disfunction, extra finger or toes, and other symptoms. It occurs in 1 of 140,000 to 160,000 North American births.
There is no cure for Bardet-Biedl Syndrome today, but having a naturally occurring animal model for the condition could help us find one in the future, said a researcher.
The discover is timely, as gene therapy is already becoming a reality for some with retinal diseases.
In the 1990s, researchers discovered dogs that had a gene mutation linked to a congenital blindness-causing condition called Leber's congenital amaurosis.
The animal model played a key role in helping researchers develop what became the first FDA-approved gene therapy for an inherited disease in December 2018. Neuringer's group also hopes to develop a similar therapy for BBS.
After Neuringer and colleagues discovered two related monkeys without cells that are key to vision, OHSU nonhuman primate genetics experts examined the animals' genomes. They quickly found both monkeys had a mutation of the BBS7 gene, one of at least 14 genes associated with BBS.
Because the geneticist leads an effort to genetically sequence 2,000 rhesus macaques at the nonhuman primate research centre, they were also able to search the genomes of numerous other monkeys there.
As a result, the team found a third monkey with the same mutation. The third rhesus macaque already had serious vision loss when it was identified in 2018 at age three and a half, although it adapted so well among its social group that the vision loss wasn't obvious.
Neuringer's team is observing the 3rd monkey over time to better understand how the disease progresses in rhesus macaques.
