Overview
Both environmental and genetic factors appear to be involved in the development of tetralogy of Fallot.
Causes
Common Causes
- Environmental Causes or Influences
- Alcoholism in the mother
- Diabetes
- Clomifene
- Pregnancy after the age of 40
- Poor nutrition during pregnancy
- Rubella or other viral illnesses during pregnancy
- Phenylketonuria (PKU) in the mother
- Fetal hydantoin syndrome
- Fetal carbamazepine syndrome
- Genetic Causes
- There is a high incidence of chromosomal disorders in children with tetralogy of Fallot.
- Tetralogy of Fallot is associated with:
- Down syndrome
- DiGeorge syndrome (a 22q11.2 deletion, a condition associated with heart defects, hypocalcemia, and immune deficiency)
- A gene polymorphism at the methylenetetrahydrofolate reductase (MTHFR) region has been associated with tetralogy of Fallot.[1][2]
