Hi,
Yes, there may be greater chance for birth defects when marriage between cousins occurs (>2%) when compared to individuals having no blood relation.
Infant mortality also may be higher in cases of marriage between cousins.
Consult your genetic counselling unit, they will examine and guide you accordingly.
Hope I have answered your query. Let me know if I can assist you further.
