Organizational Update

2023 has been a big year so far, and as we look ahead at these last two months, we review the landscape of where we are and where we need to be.  We are laser focused on building our community, furthering the coordinated clinical care we’ve established, and driving our research efforts towards our ultimate goal of a treatment.
 
Discover more up-to-date information on Kleefstra Syndrome by watching the presentations from our 3rd Annual Kleefstra Syndrome Family + Scientific Conference!  From sleep studies to seizures, digital natural history studies to antisense oligonucleotide (ASO) treatment potential, the conference covered information that is impacting patients, families, and caregivers on a daily basis.
 
We are looking forward to closing out 2023 strong!
