Is there a way of knowing if any genetic disorder will be passed on to children, when marrying a first cousin?

I am looking for blood tests or other tests which can be done on both partners to predict if any genetic disorders will pass on to their children after they get married and decide to have children.

Marriage between first cousins is legal in most countries and states within the United States. However, if you know that certain diseases are prevalent in your family or suspect that either of you could carry a genetic disease, expressed or unexpressed, then you should consult with a genetic specialist for karyotyping.

In this, samples of your blood are collected and checked for certain known markers and you will receive counseling regarding the results.

Glad to help. With the exception of hereditary conditions or diseases, recent studies show that even when siblings bear children together (not my cup of tea) the risk of offspring being born with abnormalities or deformities is NOT significantly greater than had they borne children with non-family. Report It

You would need to see a genetic specialist for this, sorry. I am sure there are tests that can be done to see if either of you carries the gene for them, but remember all conditions must be met for the disease. Personally, I thought people were not allowed to marry within their own family.

You mean, besides the fact that is is not legal in most states?
There are blood tests for genetic disorders but whether they will pass on to the offspring is always a crap shoot.
The likelihood of passing on genetic flaws multiplies when cousins marry. I don't know by what factor, but is is significant.
