IMPACT-Ready Study

6 november 2026 bijgewerkt door: Coalition for Aligning Science

Aligning Research to Impact Autism (ARIA) Innovative Medicine and Precision Approaches to Clinical Trials (IMPACT)-Ready Study

The IMPACT-Ready Study is a multi-site, international short-term prospective natural history study to develop new outcome measures, clinical endpoints, and biomarkers for autism and related neurodevelopmental conditions. The primary objective is to systematically document over time the behavioral, medical, neurophysiological, and genetic presentation of children with profound autism and related neurodevelopmental conditions. Participants will be initially separated into two cohorts: those with a confirmed diagnosis of a monogenic disorder associated with profound autism, including ARID1B, GRIN2B, RNU4-2, SCN2A, SLC6A1, or other genes of interest (Cohort 1), or those with likely profound or profound autism without a definitive genetic cause for their autism at the time of enrollment who use few or no words to communicate, with significant cognitive impairments (Cohort 2).

All participants will complete a baseline visit, and a subset of participants will complete either 6-month or annual follow-up visits based on the results of their genetic testing and their age.

After whole genome sequencing and Fragile X testing at the baseline visit, Cohort 2 will be split into 2 groups: Cohort 2a (those with a definitive genetic cause for autism not identified) and Cohort 2b (those with the presence of pathogenic or likely pathogenic variant(s) in a neurodevelopmental gene other than one of the targeted genes of interest AND those that do not meet the criteria for profound/likely profound autism following baseline assessment).

Gedetailleerde beschrijving

The ARIA IMPACT-Ready Study aims to better understand and measure how autism and related neurodevelopmental conditions develop and change over time. What we learn may help improve future research and treatments. Eligibility criteria is children ages 0-18 years who have a pathogenic or likely pathogenic variant in ARID1B, GRIN2B, RNU4-2, SCN2A, SLC6A1, or other genes of interest AND children ages 2-18 years who have likely profound or profound autism with no known genetic cause and use few or no words to communicate (are minimally verbal or non-verbal), with significant cognitive impairments. Participation lasts up to 2 years, and depending on the child's age, it involves 1 to 5 study visits. Each visit will last between 5-8 hours and may be split over 2 to 3 days, if needed. During the study, participants will:

  • Provide a blood or cheek swab sample for whole genome sequencing (WGS). The blood or cheek sample is also required from biological parents, if available.
  • Complete physical and neurological exams
  • Participate in play-based activities and surveys to better understand cognitive (IQ), behavioral, and developmental skills.
  • Participate in studies to examine biomarkers of brain function, such as electroencephalography and eye tracking
  • Wear a smartwatch, an EEG headband, and have a thin mat placed under their mattress to monitor their sleep at home for 3 nights.
  • Parents will also be asked questions about their child's family and medical history.

Families receive a detailed behavioral report, genetic testing results and $250 for each completed visit. Reasonable travel costs will be covered.

Cohorten en interventies

Groep / Cohort
Cohort 1

Children and young adults (birth to 18 years) with confirmed pathogenic or likely pathogenic variants in genes strongly linked to autism, including ARID1B, GRIN2B, RNU4-2, SCN2A, SLC6A1, or other genes of interest. A formal diagnosis of profound autism is not required to participate. This group will be followed over time.
Cohort 2a

Children and young adults (2-18 years) with likely profound or profound autism without a definitive genetic cause for autism identified from whole-genome sequencing or Fragile X testing at the baseline visit. This cohort will be followed over time.
Cohort 2b

Children and young adults (2-18 years) with either 1) likely profound or profound autism with the presence of a genetic variant(s) in a gene other than one of the targeted genes of interest or another gene known to cause autism or 2) do not meet the study definition for profound/likely profound autism following baseline assessment. Meaningful genetic, clinical, and biomarker data will be collected from these participants at the baseline visit, but this cohort will not be followed over time.
