Product Description

  • Test for 76 autosomal recessive conditions

Description

Are you a carrier for a disease which could be passed to you children? Our carrier status test will test for 76 autosomal recessive conditions.

Autosomal diseases are caused by a mutation in a single gene. Autosomal recessive diseases, however, do not affect the carrier, but could possibly be passed to the next generation if both parents are carriers. If both parents are carriers, than the risk of their child having the disease is 25%.

Understanding Recessive Diseases

In an autosomal recessive scenario, both copies of a gene need to be mutated in order for the disease to be expressed. This means that the disease will occur in that person’s life, and in most cases regardless of environmental factors. These mutations can be carried in families for generations without detection.

Look at the diagram to the right:

As you can see in the family on the right side both mother and father are carriers. The reason they don’t have the disease is that they need two copies of the mutated gene in order for the disease to be expressed.

If this couple has a child, they would have a 25 % chance of having a normal child who isn’t a carrier, 50% chance of having a child who is a carrier (someone who is like them), and 25 % chance of having a child that will express the disease. Remember we inherit 2 copies of each gene, one from our father and one from our mother. Since we inherit 2 copies of each gene if one of the copies is not mutated then they are usually safe.

The test is performed when each person provides a small saliva sample. This consists of an individual spitting into a small plastic tube. The total amount collected is approximately 5ml. The storage case helps preserve the sample until it reaches the lab for testing. The tests can be done in office or in the comfort of your own home. This is a valuable test to all prospective parents. We believe this test is valuable to anyone who would like to know his or her carrier status.

“DNA may also be collected through other means. Common forensic samples are hair (must have the root ball attached), mucous on a tissue, earwax and toothbrushes. However the cost will be on average $100 extra.”
