In this study, the researchers used data from publicly available data bases: Simons Foundation Powering Autism Research (SPARK), which includes autistic individuals and their unaffected siblings; Genotype-Tissue Expression (GTEx) and 1000 Genomes (1000G). They found specific Neanderthal genetic markers were enriched in people with autism compared to ethnically-matched control groups.
