Validation of a Salivary miRNA Diagnostic Test for Autism Spectrum Disorder
This study involves sample collection to identify biomarkers relating to Autism Spectrum Disorder(ASD) in the saliva of children who are between the ages of 18 months to 6 years and 11 months. Participants will at each timepoint have a non-invasive saliva swab collected and complete a brief demographic and medical history questionnaire as well. Children in the pediatric/provider setting who will receive a referral for an ASD diagnosis because they were determined to have a suspicion of developing ASD will be enrolled in the study. Children will also be enrolled in the specialist evaluation setting where they will receive a DSM-5 diagnosis. A subset of both enrollment cohorts will also be followed up with at a third time point in which their diagnosis will be confirmed, and information about any ongoing treatment will be gathered.
• 18 through 83 months old
• The study will include children at risk for ASD as defined by meeting one or more of the following criteria:
‣ flagged positive on a developmental screening tool (see below for assessment cut off scores)
⁃ the child has a biological sibling with ASD
