These included genes associated with behaviorally important substances such as glucocorticoids [34], GABA [14], [49], [50], septin [15], calcineurin [51], as well as the genes CNTNAP2 (implicated in language delay in autistic children [52]) and FOXP2 (known to be involved in vertebrate communication [17], [53]–[55]). This evidence concerns the gene CNTNAP2 and Delayed speech and language development.
