There are two main ways in which genetic diseases are referred to. They are, Dominant inheritance, and Recessive inheritance.
When a disorder is dominant, there is a 50% chance that the gene will be passed on to the child from the parent.
When a disorder is recessive, the gene will only manifest if 2 copies of the gene are inherited, one from each parent. A child with a recessive gene has a 25% chance of inheriting both copies of the defective gene and a 50% chance of inheriting just one copy of the defective gene from either parent.
The Inherited Disease DNA Test examines over 700 inherited diseases, including cardiovascular, developmental, metabolic and neuromuscular, and can be used as a precautionary tool, or to test prospective parents for inherited conditions.
If used as a preconception test, both partners are tested for a wide range of genetically inherited diseases. Doing this before you conceive allows for a wider range of options prior to falling pregnant.
