CHARGE association, a rare congenital condition, may be linked to increased paternal age at birth. This finding suggests potential genetic causes like dominant mutations in affected families.

Area of Science:

  • Genetics
  • Pediatrics
  • Medical Genetics

Background:

  • CHARGE association is a complex congenital malformation syndrome with an unknown etiology.
  • Previous research has not identified specific causative factors for CHARGE association.

Purpose of the Study:

  • To investigate potential etiological factors for CHARGE association.
  • To explore the relationship between parental age and the occurrence of CHARGE association.

Main Methods:

  • Retrospective case series analysis of 41 patients diagnosed with CHARGE association.
  • Comparison of mean paternal and maternal ages at birth between CHARGE patients and a control population.

Main Results:

  • A statistically significant increase in mean paternal age at birth was observed in CHARGE patients (33.7 years) compared to controls (30.8 years).

  • No significant difference in maternal age at birth was found between CHARGE patients and controls.

    • Conclusions:

    • Increased paternal age may be a risk factor for CHARGE association.
    • The findings suggest a potential role for dominant mutations or subtle chromosomal abnormalities in the etiology of CHARGE association.
