Evidence for inheritance in patients with VACTERL association.


VACTERL/VATER association is typically a sporadic disorder. We present data on inheritance in 78 probands with VACTERL association, and show that 9% of probands have a primary relative with at least one component feature of VACTERL association. The prevalence of component features in first-degree relatives is significantly higher than expected in the general population, which has implications for counseling of affected families and for research into possible etiologies.
