Our findings identify gender-dependent mechanisms of OXTR rs53576 gene variation impacting the functional connectivity of the hypothalamus in healthy individuals and suggest that these mechanisms are important for understanding ASDs.
It was expected that risk-allele-carriers of the oxytocin-receptor-gene-polymorphism (rs53576) and of CD38 (rs379863) responded similar to upright and inverted faces as persons with ASD.
Our aim was to evaluate the influence of two polymorphisms (rs1042778, rs53576) at the oxytocin receptor gene (OXTR) on ASD diagnosis and on specific ASD-related clinical symptoms (seizures, panic, and aggressive behaviors).
