here are details

Detailed Answer:
Thanks for the query.
There are 6 percent chances of having some birth defect(related marriage) specially autosomal recesive character in comparision of 3 percent in normal population.
Some diseases like cystic fibrosis, spina bifida are 1 to 1.5 percent more likley to occur in couples which are relatives or cousines.
But nothing to worry, as the disorders may occur in normal populations also.
Age of women also carries risk of getting birth defect, like more defects in 40s than 30s.

Yes you can do some test like genetic counselling and screening for haemoglobinopathies.
There only 3 percent extra risk becuase general people also have 3 percent risk.
So i would suggest you to go ahead after genetic counselling.
Hope i helped you.
