>Low iron intake significantly interacted with advanced maternal age and metabolic conditions; combined exposures were associated with a 5-fold increased ASD risk.
Maternal age and iron intake aren't genes. Neither is folate:
Their final analysis had N=209; is that a large enough sample considering the prevelance of ASD? Or does their use of the SRS scores (as opposed to a boolean "on the spectrum") get around that?
