Starrysky- there are other abnormalties that parents are not cousins and a child can be born with. Me and hubs are first cousins and our family is full of cousin marriages. Yes there are chances for genetic conditions but it's not to say that a person with no cousin marriage will have a normal baby. My close friend's baby was born with holes in her heart and severe hydronephrosis..They are goras and not remotely releated.. I don't think it's fair to scare of people by telling them that there can be consequences. It's better to pray to Allah and hope everyone has a beautiful healthy child.
You are right, everyone gets problems. However, the problems I am referring to are autosomal recessive ones that have a very clear inheritance pattern. It is a fact that those conditions have a much higher prevalence in areas with high consanguinity (i.e. cousin marriages) compared to other populations. I'm not making up things to scare people. Your family is lucky they haven't had any problems. But if your future generations keep marrying cousins then the problem gets a lot worse.
1 in 25 Pakistanis are carriers for thalassaemia and the prevalence of the disease is so high in Pakistan, it makes me very sad. If people got blood tests done before they got married (like they do in places like Iran, Saudi) then we could quite easily eradicate this devastating condition.
I don't have an issue with cousin marriages per se, my own brother is married to my first cousin and mA they have 3 healthy children. I'm just pointing out that we have more of these autosomal recessive diseases because cousin marriages are EXTREMELY common amongst us. And as educated beings we should make an effort to change the situation.
