Our Mission
IDefine is dedicated to accelerating Kleefstra syndrome (KS) research through building community, developing standardized clinical care, and creating pathways for researchers to navigate that are enabled by our efforts
Our goal is to accelerate discoveries in KS research toward clinical testing with the goal of improving the lives of individuals with KS and their families. To do so, we have created iPSC model systems and biosample repositories while organizing family and scientific conferences to drive ideas forward.
Funding Opportunities
Currently Open: IDefine Advanced Cell Modelling Request for Applications (RFA)
IDefine, the Kleefstra Syndrome Foundation, seeks to applications that aim to use advanced in vitro cellular models to better understand Kleefstra syndrome (KS), and to develop a system that could be used in the future to screen and validate potential KS treatments. The funded project will receive $100,000 (USD), with a potential extension of an additional $100,000 in year two. Pre-existing iPSC lines will be provided for use in the funded project.
Get Involved
Growing our census of individuals with Kleefstra syndrome enables us to display our community engagment, connect, and provide visibility to current and future partners the number of families they could impact.
Medical records hold Important information on Kleefstra syndrome that could accelerate research. You can unlock those records and contribute them to research in a private and secure way.
The Simons Searchlight Registry is for individuals with a confirmed Kleefstra syndrome diagnosis. By joining the registry, you encourage research on EHMT1 and Kleefstra syndrome.
Begin the first step in making your patient information available to researchers. RARE-X is a data collection platform that asks general questions on all body systems in a series of “head to toe” surveys.
For Researchers
Kleefstra Syndrome is an excellent model system for drug development in the ID space:
- A single gene causes KS (EHMT1), and it has been extensively studied
- There has already been substantial scientific research on the underlying mechanisms of KS, and there is a highly active community of researchers
- EHMT1 is involved in epigenetic regulation, an area of research that has seen substantial investment and drug development in the last decade
- Epigenetic regulation appears to be a key factor in multiple ID syndromes, so development of a treatment for KS may inform options for other syndromes
- There is a very active community of KS families, opening the door to clinical study recruitment when a potential therapy has been identified
In consultation with our Scientific Advisory Board, we will pursue the most promising avenues for drug development, and “go where the science takes us”. A range of approaches are being reviewed, including small-molecule drug repurposing, small molecule drug development, oligonucleotide-based therapies, or gene therapies.

Eric, Isaac’s father, is a scientist and software professional with more than 20 years of experience spanning molecular biology, bioinformatics, and genomics. He received his Ph.D. from the University of California San Diego (UCSD) and performed original research at UCSD and the Salk Institute. He has authored numerous research articles, many of which are highly cited in their fields, as well as several book chapters.
Eric pairs this rich scientific research background with substantial experience in the business world, including roles in product development, sales, and marketing. He has focused his career on delivering software solutions to researchers that help enable them to make the next round of scientific discoveries. He is currently the global Product Manager for Biological Interpretation at Illumina, the world’s leading genomics company. There he helps guide the development of Illumina’s software solutions for downstream interpretation of genomic data.
Eric happened to sit next to Darrick at the Kleefstra Syndrome family conference hosted by Kid’s IQ Project, and they hit it off immediately and exchanged phone numbers. Some months later Eric received a message from Darrick about the concept of IDefine. His simple reply was, “Sounds great. I’d like to get involved.” He is delighted that he can leverage his background to help this remarkable team develop a vigorous research program focused on finding new life-changing treatments.

Paul, Edward’s father, is an accomplished pharmacologist with extensive pharmaceutical industry experience across all phases of the R&D process. Dr. Smith received his Ph.D. in Immunology and Neuroscience at Imperial College London, UK and a B.Sc. in Pharmacology from the University of Bath, UK. Dr. Smith has more than 15 years of drug discovery experience primarily focused on the treatment of inflammatory and autoimmune diseases, and he is an inventor on fifteen issued or pending patents. He is currently the Vice President of Discovery Biology with Connect Biopharma. Prior to his career with Connect Biopharma, Dr. Smith was Senior Director of Inflammation and Autoimmunity at Incyte Corporation where he established the discovery research team.
Paul, the initial member of IDefine’s SAB, feels right at home in his position on the SAB. “I’m not just a guy on a scientific advisory board helping out with some scientific questions,” Paul said. “I’m a parent, I see Eric and Geoff as my friends, and I see them as people with a common goal and an infectious energy. I want to be working with them, it’s not an obligation.”

Prof. Tjitske Kleefstra
In 2010, Dr. Kleefstra and her research team identified the genetic cause for the set of characteristics associated with what is, after her work, known as Kleefstra Syndrome (KS).
Dr. Kleefstra continues her work to improve diagnostics, management and treatment for patients with neurodevelopmental disorders, particularly those resulting in intellectual disabilities. She leads a research team focused on developing individual approaches to treating and managing these disorders, working to construct personalized healthcare for patients diagnosed with rare conditions.
Dr. Kleefstra remains an active participant in the KS community, building bridges between researchers and the families affected by KS and other intellectual disabilities. She provides monthly updates to the IDefine team and their colleagues, ensuring access to the latest scientific developments in her work. She sees great potential in IDefine’s capacity to bring teams of scientists and doctors together to work toward funding research and clinical trials for life-changing treatments and therapies for those diagnosed with KS.
“It is a great honour for me to highlight the launch of IDefine, the first US based, but globally supported, charity focused on fundraising for research on the Kleefstra Syndrome!
The syndrome that I, together with my colleagues in Nijmegen, The Netherlands, study intensively after we identified 15 years ago the causal genetic factor: the EHMT1 gene!
Only by joining world-wide efforts can we move this field on a RARE disorder forward to challenge the various aspects we all face.
It is difficult to foresee where we are in another 15 years, but we may expect huge steps that now only seem magic!
Thanks to all who made IDefine possible and looking forward to a well connected future!”

Dr. Nael Nadif Kasri
Dr. Nael Nadif Kasri, is a neurobiologist who has extensive experience with the molecular mechanisms underlying synaptic plasticity, including imaging and electrophysiological methods in cellular and animal models. Since the start of his postdoctoral studies he has been interested in understanding the molecular mechanisms of neurodevelopmental disorders. In his postdoc he mainly focused on understanding the function of Intellectual disability (ID) genes related to the RhoGTPase pathway and he was among the first to posit that ID disorders are disorders of the synapse.
When starting his lab in 2011 at the Radboudumc, he joined the Human Genetics department (Nijmegen, the Netherlands) where he started several collaborations to understand the synaptic basis of ID. As such he has focused his research on several syndromes that were initially discovered in Nijmegen, being Kleefstra syndrome and Koolen-de Vries Syndrome. One of his recent contributions is the implementation of multi-electrode recordings in human induced pluripotent stem cells. This technique enables the stratification of patients who suffer from autism, which may lead to more specific therapies.
Dr. Nael Nadif Kasri was awarded with a Human Frontiers fellowship at Cold Spring Harbor Laboratories (USA), where he performed his second postdoctoral study. Since 2011 he has his own research group at the Radboudumc, and became part of the Donders Institute in Nijmegen, the Netherlands. There he was granted a prestigious Hypatia fellowship and a Marie Curie Career Integration Grant.
