Thanks for taking my question.?
?
I have read two studies: One linking low serotonin to agression in males, and another linking low serotonin to SIDS in infants.?
?
I was wondering if it is possible for an agressive father to pass along the gene for a defective serotonin receptor to his child, which then leads to SIDS.?
?
The two studies are the following:?

Why are some men more aggressive?:?

Dr. Joshua’s Answer:

B.L. Jacobs and C.A. Fornal, in their article Serotonin and Behavior: A General Hypothesis (1995) said: “Serotonin is an enigma. It is at once implicated in virtually everything, but responsible for nothing”.

Serotonin as a neurotransmitter participates in many neurologic and behavioral functions, but often we cannot pinpoint the exact mechanism by which serotonin exerts its effects. There is no evidence that a single gene is responsible for aggressiveness, and while the risk of sudden infant death syndrome is known to be increased in some genetic syndromes, the cause of the majority of SIDS cases is not known.

The short answer to your question is no, there is no such gene that would link a father’s aggressiveness to sudden infant death. Whether such a gene could theoretically exist, I don’t know, but I seriously doubt it.
