Summary
A novel FGFR1 gene variant was identified in a fetus with severe spina bifida, suggesting a potential role for FGFR1 in neural tube defects. Further research is needed to confirm this link in larger patient groups.
Area of Science:
- Genetics
- Developmental Biology
- Medical Research
Background:
- Neural tube defects (NTDs) are congenital malformations with genetic and environmental causes.
- Monogenic causes of NTDs are increasingly identified, especially those affecting morphogenetic pathways.
- FGFR1 is vital for development, but its role in caudal dysraphism is not well understood.
