This type of inheritance is called autosomal dominant. In this situation, the parent with the abnormal gene has PKD. Because he or she also has a normal gene, however, not all of the person's children are affected.

These reports suggest autosomal dominant transmission with a mildly affected parent having a more seriously affected child. The chance is from 2 to 5% that a child whose sib has de Lange syndrome will also have the syndrome.

Hereditary amyloidosis is though to be autosomal dominant, which means that only one copy of the defective gene is necessary to cause the disease. A child of a parent with familial amyloidosis has a 50-50 chance of developing the disease.

Symptoms can begin from adolescence to around age 40. It is caused by an autosomal dominant trait (at least one parent will have the disease). Progression is usually slow and severe disability is unusual.

It is passed along genetically as an autosomal dominant trait, which means there is a 50 percent chance of inheriting this condition if only one parent is affected. Again, while not generally debilitating, it can be a risk factor for combat pilots.
