Hemifacial microsomia: from gestation to childhood

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatric Medicine

Background:

• Hemifacial Microsomia (HFM) is a complex congenital malformation characterized by facial and ear asymmetry.
• Etiology and long-term consequences of HFM remain incompletely understood.
• This research investigates risk factors and sequelae of HFM through multiple studies.

Purpose of the Study:

• To identify maternal exposures associated with HFM risk.
• To explore genetic variations linked to HFM.
• To characterize the psychosocial, cognitive, dental, and medical outcomes in children with HFM.

Main Methods:

• Case-control study analyzing maternal interviews on exposures during the first trimester.
• Genetic analysis of DNA from a previous study to assess variations in vasculogenesis and hemostasis pathways.
• Longitudinal observational study with questionnaires for mothers and teachers assessing child development.

Main Results:

• Maternal use of vasoactive medications, especially with cigarette smoking in the first trimester, showed an association with increased HFM risk.
• Preliminary data suggest children with HFM may have poorer academic performance and increased internalizing behaviors.
• Ongoing genetic and longitudinal studies aim to further elucidate HFM etiology and impact.

Conclusions:

• Maternal exposures, particularly vasoactive medications and smoking, are potential risk factors for HFM.
• Children with HFM may face developmental challenges requiring further investigation.
• Comprehensive research is crucial for understanding and managing Hemifacial Microsomia.
