About KDM5C

KDM5C disorder, also known as Claes-Jensen syndrome, is a rare genetic condition caused by a mutation in the KDM5C gene. It is an X-linked neurodevelopmental disorder that leads to a range of symptoms affecting development, behavior, and physical health. Key features often include intellectual disability, developmental delays, seizures, and behavioral problems.

What is an ASO?

An ASO—“antisense oligonucleotide”—is a precisely designed genetic molecule that helps correct how a gene sends its message. For children like Birdie, ASOs have the potential to restore some of the function lost due to the mutation, improving development, cognition, behavior, and overall quality of life. 

Our Partners 

We are partnering with n-Lorem to fund and support the research necessary to determine if there is a therapeutic strategy for Birdie’s mutation, and if successful to support the development of an ASO medicine to treat her.
