Spina bifida as a multifactorial birth defect: Risk factors and genetic underpinnings

Area of Science:

• Developmental Biology
• Genetics
• Environmental Health

Background:

• Spina bifida is a severe birth defect impacting neural tube development.
• Myelomeningocele, the most severe subtype, significantly affects quality of life.
• Etiology is complex, involving numerous unknown genetic and environmental factors.

Purpose of the Study:

• Review current research on spina bifida risk factors and genetics.
• Elucidate the complex etiology of this congenital malformation.
• Highlight emerging insights into gene-environment interactions.

Main Methods:

• Literature review of recent studies on spina bifida.
• Analysis of genetic and environmental risk factors.
• Discussion of new genetic sequencing technologies.

Main Results:

• Folic acid and food fortification are preventive but insufficient due to confounding factors.
• Environmental pollutants, medications, and maternal conditions (diabetes, obesity) impact prevalence.
• Gene-environment interactions influence susceptibility to risk factors.

Conclusions:

• Understanding intricate gene-environment interactions is crucial for spina bifida prevention.
• New genetic technologies offer potential for large-scale gene discovery.
• Effective prevention and intervention strategies require a comprehensive understanding of multifactorial risks.
