Get to Know Me

Angie Duker, MS, LCGC, is a genetic counselor in our skeletal dysplasia program. She’s been a genetic counselor since 2003 and with Nemours since 2010, where she coordinates the skeletal dysplasia clinic. Angie has been involved in many research projects over the years, but now mainly focuses on primordial dwarfism. She’s board certified by the American Board of Genetic Counselors, and a graduate of the University of Wisconsin and the University of Michigan, where she earned her MS in Human Genetics. Angie is on the medical advisory boards of Little People of America, Potentials Foundation, and Walking with Giants Foundation. In her role with the skeletal dysplasia team, she loves working with great families from all over the world, helping them get the information they need to help their child reach their utmost potential.

Why I Treat Children

I became enamored with genetics in 7th grade, after having an amazing science teacher. I also love working with kids. Once I discovered medical genetics, and pediatric genetics specifically, it seemed to be the perfect match for my interests. Though there are many different areas for a genetic counselor to work, I can’t imagine being anywhere but pediatrics … especially now that I am a parent myself. It is incredibly rewarding to help parents (and children themselves) understand more about genetic conditions in their family.

What I'm Passionate About

I feel very lucky to have joined the skeletal dysplasia team in 2010. I work with an amazing team of collaborative multidisciplinary providers and fantastic families. I’m passionate about helping families with children with dwarfism wrap their heads around new diagnoses, and getting them set up for success in the future. Our team is involved with the Little People of America organization, and it’s great to be able to connect families to this group and the wider LP community in the world. Families consider us their dysplasia medical home, and being able to follow children over the years and watch them grow both physically and emotionally is very gratifying. 

How I Try to Make A Difference

Many families come to us (from all over the country and the world) after being unable to find experienced care locally. It is an amazing feeling to almost hear the deflation of anxiety over the phone as I answer whatever questions families have about a particular diagnosis. I’m often focused on helping families understand the importance of, and get the tools to follow through with, care plans and overall medical management for the care of their child. As parents, we want nothing but the best for our children — and I’m happy to be the person to help families get on the right path to feel reassured that they are doing all they can do.

Research Activities

Our team is involved in clinical research involving many different types of skeletal dysplasias. My biggest research focus now is on primordial dwarfism. Specifically, we coordinate an international Primordial Dwarfism Research Registry. Through that I have participated in myriad studies with the goal of formulating care plans to help identify and treat any contributing causes of illness or life-threatening situations. It seems like as soon as we figure something out, the door opens for something else to learn about … which is both the blessing and the curse of research! However, it’s one that I enjoy very much, and am happy to be a part of if it means making the lives better of the children and families I work with.
