A trusted space for parents, caregivers, and communities to learn, connect, and support children living with ADNP Syndrome.
This platform is dedicated to raising awareness, providing resources, and building a strong, supportive network for families navigating ADNP Syndrome.
We aim to empower parents with knowledge, connect families worldwide, and support ongoing research efforts to improve the lives of children with ADNP.

ADNP Syndrome, also known as Helsmoortel-Van der Aa Syndrome (HVDAS), is a very rare genetic condition that affects brain development. It is caused by changes (mutations) in the ADNP gene, which plays a critical role in how the brain forms, functions, and protects nerve cells.
The ADNP gene is important for processes such as neuron communication, brain cell structure, and cellular protection. It also plays a role in other body systems, meaning its effects are not limited to the brain alone.
ADNP is considered one of the more commonly identified genes linked to autism spectrum disorder (ASD). Research has also shown that levels of ADNP protein may be reduced in individuals with Alzheimer’s disease, highlighting its broader importance in brain health.
Children with ADNP Syndrome may experience a wide range of challenges. These can include developmental delays in speech, learning, and motor skills, as well as differences in behavior such as autism-related traits. The condition may also affect multiple systems in the body, including the heart, immune system, digestion, sleep, and growth.
Current estimates suggest that ADNP Syndrome affects approximately 1 in 27,000 children in the United States and Europe. Both boys and girls can be affected, although slightly more cases have been identified in boys. Because it is so rare, the full scope of the condition is still being studied.
Testing: There is no single dedicated test specifically for ADNP Syndrome. However, the ADNP gene is now included in many genetic testing panels for developmental delay and autism through laboratories such as GeneDx and Ambry Genetics.
Unique Early Sign: One notable feature observed in many children with ADNP Syndrome is early tooth eruption. Studies have shown that a large percentage of children develop a full set of baby teeth much earlier than expected, sometimes within the first year. This uncommon pattern may help support earlier identification of the condition.
Every child with ADNP Syndrome has a unique story. Here are some of the amazing kids who inspire our community every day.
