Fetal growth restriction: a workshop report

Area of Science:

• Obstetrics and Gynecology
• Developmental Biology
• Genetics

Background:

• Intrauterine growth restriction (IUGR) is linked to adverse perinatal outcomes and later-life health issues, including cardiovascular disease and glucose intolerance.
• Diverse factors, including genetic, metabolic, vascular, coagulative, autoimmune, and infectious disorders, can impair fetal growth by affecting placental function.
• Accurate definitions of IUGR and its severity are crucial for differentiating phenotypes based on onset, degree of restriction, and hypoxia presence.

Framework:

• This review examines recent clinical and basic research on IUGR mechanisms.
• Focus areas include genetic factors, utero-placental nutrient supply, and vascular growth factors.
• Investigates genomic imprinting defects and placental anomalies affecting nutrient transport.

Implementation:

• Summarizes new findings on genomic imprinting defects associated with IUGR.
• Highlights placental anomalies contributing to reduced nutrient transport.
• Discusses recent data on angiogenic growth factors and gene chip technologies.

Implications:

• Advances understanding of IUGR etiology and pathogenesis.
• Potential for improved diagnostic criteria and therapeutic strategies for IUGR.
• Facilitates identification of at-risk pregnancies and development of targeted interventions.
