In brief: We don't know
In most cases tetralogy of fallot is thought to be "multifactorial", meaning that there are possibly genes, and also environmental factors which might increase a child's potential of having the defect.

In brief: Multiple factors
It is still unclear what causes tof.
There are both genetic and environmental factors that appear to increase the risk: poor maternal nutrition; alcohol consumption; maternal age > 40; maternal diabetes; maternal rubella; genetic disorders/syndromes (down syndrome or digeorge syndrome); parent or previous child with tof; maternal pku; maternal use of fluconazole, tegretol, or dilantin.
