Townes-Brocks syndrome

Inheritance patterns and prenatal diagnosis

Inheritance patterns
 TBS is inherited as an autosomal dominant trait. Changes in a gene located on chromosome 16 are associated with the characteristic features.

Prenatal diagnosis
It may sometimes be possible to perform prenatal diagnosis by chorionic villus sampling (CVS) or amniocentesis during pregnancy. Genetic counselling may be helpful for individuals and families affected by this condition.
