Using the assumption of a general dysregulation of steroid hormones as a starting point to elucidate the role of CYP17A1 activity in depth, Table 1 summarizes the steroid hormones of interest for a sample of 48 boys with autism versus an individually-pairwise matched cohort of healthy boys and, in addition, 21 girls with autism versus an individually-pairwise matched cohort of healthy girls. This evidence concerns the gene CYP17A1 and autism.
