medicine (see, 5. Functional Genomics). The broad scope of COGA sample ascertainment, banking and analyses coupled with routinely updated phenotypic and genomic data now permit genetic, neurodevelopmental, and neurophysiological analyses of highly selected groups of COGA samples either as DNA, RNA, or iPSC‐derived neuronal derivatives. Researchers who are not formally part of COGA may submit a request to collaborate and, if approved by COGA and NIAAA, will receive selected biosamples at very modest cost (see, how to access COGA data at: https://cogastudy.org/resources-for-researchers/).
