Is Waardenburg syndrome caused by inbreeding?
No. Waardenburg syndrome type 1 is an autosomal dominant condition. Consanguinity refers to the genetic relatedness between individuals descended from at least one common ancestor.
How is Waardenburg syndrome inherited?
Inheritance. Waardenburg syndrome is usually inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with the condition.
Does Paris Jackson have Waardenburg syndrome?
