Recessive conditions are conditions that result from two recessive genes being passed to a child - one
from each asymptomatic parent - that cause a disease in that child. Current technological advances
now make it possible to test for approximately 176 recessive conditions, each with its own severity,
chance of inheritance, and sensitivity to screening. The total chance of having a child affected with one
of these diseases is about 1/200, depending on the ethnicity of the parents.
The decision to screen for these diseases is a personal one and depends on each couple's philosophy
and financial situation. In addition, there is a medical-legal dimension to this decision for CRM.
Because of the medical-legal issues involved we must ask you to declare your decision to screen or not
to screen for these conditions prior to beginning your infertility treatment. The test involves a blood test
on at least one of the partners. The blood test costs $350 and is not submitted to your insurance. There
is about a 60% chance that the test will show at least one recessive mutation in one of the partners.
If the test shows one partner to be a carrier of a recessive condition, the other partner would have the
blood test for $350 to see if both partners are carriers of the same recessive condition.
If you are both carriers for the same condition (about 2% Chance), you would have the option of doing
IVF with Preimplantation Genetic Diagnosis (PGD) where each embryo you make would be tested for the
condition and only embryos without the condition transferred to your uterus. IVF with PGD costs
Or you could simply conceive and have the fetus tested early in the pregnancy. If the test was positive
(1/4 chance), the pregnancy could be terminated or you could prepare for a baby with the inherited
A third option would be to use donor sperm or donor eggs to avoid conceiving a child with the recessive
