Q:

What is the Islamic view on marrying a person based on genotype?

And also if you are someone with AS,AC  

genotype but you love someone who turn out not to be AA genotype, what to do?

A:

I don’t have sufficient information to determine and come up with a ruling on this issue. I can only state a general rule in Islam: We are allowed to choose partners based on compatibility, including genotype, as long as it has a scientific basis.

Islam encourages us to resort to beneficial treatments and choices in life as long as such options do not contradict any of Islam’s established principles.

Almighty Allah knows best.
