Design outcomes

Primary

MeasureTime frameDescription
Correlation of Microbiome to Autism via Relative Abundance Found in Microbiome Sequencing1 yearRelative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized among specific Autism Spectrum Disorders

Secondary

MeasureTime frameDescription
Validation of Sequencing Methods1 yearTo validate the methods used to sequence samples
