Inflammatory factors, genetic variants, and predisposition for preterm birth

Area of Science:

• Genetics
• Immunology
• Reproductive Medicine

Background:

• Preterm birth affects 11% globally, causing significant neonatal mortality and morbidity.
• The etiology of spontaneous preterm birth remains largely unknown.
• Inflammatory diseases and genetic factors are recognized risks, but molecular mechanisms are unclear.

Purpose of the Study:

• To review research on the association between inflammatory-related genes and preterm delivery risk.
• To highlight specific genetic variants linked to increased preterm birth risk.
• To explore potential shared genetic underpinnings between preterm birth and other inflammatory/autoimmune diseases.

Main Methods:

• Literature review of studies investigating gene polymorphisms and preterm birth.
• Analysis of genetic variants associated with inflammatory responses.
• Examination of gene overlap between preterm birth and autoimmune/inflammatory conditions.

Main Results:

• Specific genetic variants, including TNFα rs1800629, IL1α rs17561, and IL1RN rs2234663, show significant association with preterm birth risk.
• Many identified genes are also implicated in periodontal disease, inflammatory bowel disease, and autoimmune rheumatic diseases.
• Evidence suggests a common genetic susceptibility for preterm birth and inflammatory/autoimmune disorders.

Conclusions:

• Inflammatory-related genes play a role in preterm birth susceptibility.
• A shared genetic background may link preterm birth risk with autoimmune and inflammatory diseases.
• Further research into these genetic links could inform prevention and treatment strategies.
