It is estimated that at least 55% of British Pakistanis are married to first cousins and the tradition is also common among some other South Asian communities and in some Middle Eastern countries.

British Pakistanis are 13 times more likely to have children with genetic disorders than the general population - they account for just over 3% of all births but have just under a third of all British children with such illnesses.

Indeed, Birmingham Primary Care Trust estimates that one in ten of all children born to first cousins in the city either dies in infancy or goes on to develop serious disability as a result of a recessive genetic disorder.

Their culture predisposes BP children to genetic disease.
Is it racist to say that?
