Genetic Causes
Genetic causes of tetralogy of Fallot may include:
- There is a high incidence of chromosomal disorders in children with tetralogy of Fallot.[1][2]
- 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.
