Furthermore, the analysis of the 30-bp VNTR polymorphism in the MAO A promoter region demonstrated slight differences in anxiety levels between the women, indicating that those with a 4/4 genotype had higher severity of anxiety symptoms.
No significant associations of MAO-A VNTR with the severity of depressive symptoms (Beck Depression Inventory), anxiety symptoms (Spielberger State-Trait Anxiety Inventory), general mental health (Brief Symptom Inventory), or perceived social support (F-SozU) were found (all p > 0.10).
