Lucky gene 5-HTTLPR and postpartum depression: A systematic review

Area of Science:

• Neuroscience
• Genetics
• Psychiatry

Background:

• Postpartum depression (PPD) is increasingly prevalent, severe, and complex.
• Etiology studies have focused on social factors, neglecting biological underpinnings.
• Emerging research investigates the role of serotonin transporter (5-HTT) in PPD pathogenesis.

Purpose of the Study:

• To review recent advancements in PPD research.
• To focus on the role of the serotonin transporter (5-HTT) in PPD.
• To update knowledge on 5-HTT related pathogenesis of PPD.

Main Methods:

• Literature review of articles on PPD and 5-HTTLPR.
• Searches conducted using Web of Science, PubMed, and CNKI.
• Inclusion criteria focused on studies examining the association between 5-HTTLPR and PPD.

Main Results:

• A significant association exists between 5-HTTLPR polymorphism and PPD pathogenesis.
• Evidence indicates the Long allele (L allele) of 5-HTTLPR is linked to decreased susceptibility to PPD.
• The 5-HTT gene-related pathogenesis of PPD is an area of active investigation.

Conclusions:

• Further clinical experiments are necessary to validate theoretical findings.
• The current body of literature on this specific topic is relatively limited.
• Understanding the genetic basis of PPD, such as 5-HTT involvement, requires continued research.
