I know some families who require HIV testing for the man before even consenting to an engagement-especially if he has spent time studyng or working in the west. I think if there was a clear indication that there could be a inbreedng defect then engagement would be cancelled.

In my husband's family there is a cousin that they feel has been effected by inbreedng. There is a general consensus now among the extended family that they will only marry outside the family.

Are inbreedng birth defects common in Qatar?
