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).
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.

Inclusion Criteria * For Cohort 1: age 0-18 years with clinical documentation of a genetically-defined disorder associated with profound autism, including a pathogenic/likely pathogenic variant in ARID1B, GRIN2B, RNU4-2, SCN2A, or SLC6A1. * For Cohort 2: ages 2-18 years with profound autism or likely profound autism, either without previous genetic testing or previous testing that was non-diagnostic. Exclusion Criteria * For Cohort 1: Aged over 18 years at enrollment. * For Cohort 2: Age \<2 or \>18 years at enrollment * For Cohort 2: Participants with an established genetic diagnosis for t…
