    Is Tracheoesophageal fistula inherited ?
    ### Response:
    Is tracheoesophageal fistula inherited? In most cases, tracheoesophageal fistula (TEF) is not inherited and there is only one affected person in a family. When TEF is isolated (i.e. does not occur with any other abnormalities), it is considered a multifactorial condition (caused by a combination of various genetic and environmental factors).
