Our Story
Founded in 2020 by a group of parents seeking better answers for their children and families living with a KS diagnosis, IDefine is a nonprofit organization that exists to provide a central community for families affected by Kleefstra Syndrome (KS). We are here to share information, collaborate for advocacy, and pool resources to support life-changing treatment and intervention. We are committed to unlocking the potential of individuals living with Kleefstra syndrome.
IDefine’s global team has worked to build connections between our KS community and health professionals, inviting collaboration and fueling research for innovative treatments for those affected by this rare genetic condition.
We are intent on accelerating in research through investment and organization while simultaneously building medical expertise to further develop treatment options and care. We are working steadfastly towards a cure for Kleefstra Syndrome as well as other Intellectual Disabilities.
IDefine was created to bring about the future we know is possible for our children and others living with Intellectual Disabilities – a future in which the ones we love have the tools they need to define their own path. Our core values guide each action we take in our journey to living in this reality.
Our Mission
IDefine is a nonprofit organization dedicated to discovering life-changing treatments and cures for those with intellectual disabilities stemming from genetic disorders.
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
- 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.

Margo Metzger
Margo joined the IDefine team in the summer of 2020 to lend her communications expertise and experience as an advocate for her daughter to further the mission of finding effective treatments and support for individuals and families living with KS.
In Margo’s Words:
Tell us about the person you love who was diagnosed with KS.
My daughter Adelind is the light of my life. She has never met a stranger, and she spreads joy all over the place. She is curious, loving, and pure of heart. Addie surprises us every day with her ability to master new skills, and we expect great things from her.
When did your child receive a KS diagnosis?
Addie is 7 and after many years of searching for an answer, she was diagnosed at age 5 using whole exome sequencing.
What resources, outlets, communities were most helpful to you at that time?
UNC Hospitals provided us with the diagnosis, and then we did a lot of digging to uncover scarce resources about KS. Groups like Unique, KS.org, and KidsIQ helped us find a community of families that share our challenges. Early intervention services like occupational and speech therapies from our school system helped Addie build a foundation for success.
How has KS changed your life as a family?
Every small step of progress is cause for celebration — we don’t take anything for granted in our house. Whether it’s learning to read, singing a song, or having a good conversation, we are grateful for every gain. We also look for family activities that challenge Addie and gently nudge her out of her comfort zone so she can build confidence.
What is your biggest hope for the future?
It’s pretty simple and probably what every parent wants for their child — we hope that Addie will live a healthy, happy, productive, and independent life as an adult.

In Mason’s Words:
Tell us about the person you love who was diagnosed with KS.
Eleanor, my daughter, has challenged me to revisit my purpose. Eleanor enjoys swinging, music, and learning to walk. I think she enjoys cuddles, or she just likes to see her father really happy. 🙂
When did your child receive a KS diagnosis?
1 year old.
What resources, outlets, communities were most helpful to you at that time?
Visiting Dr. Kleefstra and KS conference in Italy.
How has KS changed your life as a family?
I’ve focused on three opposing emotions that have turned me upside-down. (1) In order to maximize Eleanor’s benefits from Health Insurance and Government Programs, I’ve focused on the negative which has been very depressing, (2) Being a visionary, planner and a controller of my future I focus on the dream – finding a cure, and (3) Being a realist, not believing in magic, not knowing her future, and realistically accepting the likely scenario of a very difficult and painful road ahead, I try to focus on accepting Eleanor on who she is – not trying to change her, enjoying her presence of who she is now without distractions of who she could be.
Eleanor inspires us to be kinder than we have ever imagined.
What is your biggest hope for the future?
To never give up on finding a cure.

Geoff, Ella’s father, is a co-founder and the CEO leading the effort at IDefine who was recently recognized as a 2021 RARE Champion of Hope.
Geoff Rhyne, CEO
Geoff Rhyne, Ella’s father, is the CEO and a co-founder of IDefine. Prior to taking on his current role in the nonprofit rare disease space, Geoff has been both a hospitality professional and entrepreneur. While working in the food and beverage industry, he co-founded a Slow Foods Chapter in Greenville, SC in 2006, and has been a featured speaker on sustainability at Furman University as well as at a TEDx conference in 2010. In 2014, Geoff hit on what would become his signature sauce and launched Red Clay Provisions. Since then, Red Clay has flourished through partnerships with major retailers and recognition from regional and national media outlets.
Geoff and his wife, a special education teacher and advocate, have two sons along with their youngest child, Ella. On February 26th, 2019, Geoff, and his wife experienced “diagnosis day” for their daughter. Ella was diagnosed with Kleefstra Syndrome, a rare genetic disorder. Instead of looking at it as a setback, Geoff viewed the diagnosis as an opportunity and purpose, feeling it was a call to duty.
Consulting with the other parents he met on his path to becoming his daughter’s greatest advocate, he and his team built a vision for IDefine to become an organization focused on improving treatment and, ultimately, finding cures for children and adults with Kleefstra Syndrome and other intellectual disabilities – a vision to change the world that has become his life’s work.
In Geoff’s Words:
Tell us about the person you love who was diagnosed with KS.
My daughter, Ella, is 2 years old and the motivation behind this work. She is determined, sweet, feisty, and silly. She absolutely adores her mother and tolerates her two older brothers and dad! Kidding aside, she is an absolute blessing for our family.
When did your child receive a KS diagnosis?
15 months
What resources, outlets, communities were most helpful to you at that time?
We worked with the Greenwood Genetic Center to get the diagnosis, and the team there, led by Dr. Roger Stevenson, is and was incredible. Visiting the team at Boston Children’s Hospital, and meeting Dr. Sid Srivastava, Kira Dies, and the rest of the team was incredibly motivating and hope inducing. Additionally, the KleefstraSyndrome.org Facebook page was a great find for my wife and I to establish connections with others in the KS family, and Hira with KIDS IQ has also been an unbelievable resource. For me, the unknown was challenging, but once we received the diagnosis, I had something specific to chase!
How has KS changed your life as a family?
I wouldn’t say we have changed as much as I would say we pivoted. My wife has been a special education teacher for 15 years, and my sister-in-law has Down’s Syndrome. We were built for this. This opportunity has provided me with an immense amount of purpose to change the world. Our family has focused on celebrating milestones, big or small, because our perspective has shifted to not take things for granted. We are kinder, more empathetic, and stronger. I love that my boys (4 and 6) will have inclusivity ingrained in the fabric of their being. We are embracing this journey and determined to realize positive outcomes!
What is your biggest hope for the future?
To solve the riddle and cure KS as well as intellectual disabilities as a whole that are derived from genetic disorders. I want to change the world.

Julie Drake, Director of Partnerships
Julie Drake, Amber’s mom, is currently a stay-at-home mom fighting for the best possible life for her daughter whose needs became more complex as she got older. She has 9 years’ experience working as a registered nurse. She spent those years working in a specialty pediatric outpatient clinic, inpatient pediatric rehabilitation, pediatric home health and a nursing home. As a nurse, Julie was passionate about helping children with complex medical conditions and their families through difficult medical procedures, traumatic hospital stays, medication management, and fighting insurance companies for necessary medical care. Being a nurse, while having her own medically complex child helped Julie relate to and understand the needs of patients and their families on a personal level. Julie has a Bachelor of Science in Nursing from Purdue University and a bachelor’s degree in Biological Sciences from Northern Illinois University. Julie is excited about joining IDefine as Director of Partnerships so she can continue to use her medical knowledge and life experience to advocate for the best possible future for those living with Kleefstra Syndrome and other genetic disorders. In Julie’s own words:
Tell us about the person you love who was diagnosed with KS
My daughter Amber is a loving happy young lady who sees the good in everyone she meets. She loves music and dancing, riding her adult tricycle, doing puzzles and splashing in the pool. She is on the adapted cheerleading team at her high school and enjoys being around her peer buddies. Amber excels at using an electronic communication device for most of her speaking needs.
When did your child receive the KS diagnosis?
Amber was 10 years old when she was diagnosed and is 15 now. I was 3 weeks out from giving birth to our third child when I got the call from the geneticist that, finally, the test came back with an answer.
What resources, outlets, communities were most helpful for you at that time?
Rush University Medical Center in Chicago was instrumental in getting us the diagnosis and the very first information we received about Kleefstra Syndrome. After that I found kleefstrasyndrome.org and the KS Facebooks groups.The Kleefstra conference in Boston in 2018 was also an enormous help in understanding the research that was going on and bringing us hope for the future.
How has KS changed your life as a family?
There have been many challenges especially as Amber has gotten older. We have always found a way to adapt and cherish all the wonderful moments we have with her. The fear we felt upon the initial diagnosis and learning about the possibility of her going through psychosis and regression became a reality for her last year. It was a very dark difficult time, but we always come out stronger. Amber’s brothers are growing up to be the kindest, most compassionate and understanding humans. They have missed out on a lot of things due to her therapy schedules, hospitalizations, etc., but they have also gained so much from seeing her persevere and shine despite all the struggles.
What is your biggest hope for the future?
Ideally a treatment would be developed that but can reverse the numerous challenges associated with KS or prevent a worsening of symptoms with age. There are children and young adults that die from complications related to having this disorder. No one likes to think about that or talk about that, but it’s a miserable reality. My biggest hope is for everyone with KS and all genetic disorders is to be able to live their best lives possible for as long as possible without suffering from the physical medical complications, psychosis, or regression.
