Genes x Environments: Atypical Symptoms

[James Brody]

Lamarck wins?!!! And so does mom!

"Review of current evidence suggests the hypothesis that developmental factors may play a role in some cases of MUS. Maternal perception of a threatening environment may be transmitted to the fetus when hormones cross the placenta and affect fetal physiology, effectively 'programming' the fetal stress response system and associated behaviors toward enhanced vigilance.

"After birth, intense stress responses in the individual may result in similar vulnerability, which may be unmasked by subsequent stressors. Epigenetic modulation of gene expression (EMGEX) appears to play a central role in creation of this 'survival phenotype'."
