Why cousin marriages can wreak genetic havoc on children

The risk of giving birth to babies with genetic defects as a result of marriages between first cousins is no greater than that run by women over 40 who become pregnant, according to two scientists who call for the taboo on first-cousin families to be lifted. Women in their forties are not made to feel guilty about having babies and the same should apply to cousins who want to marry, said Professor Diane Paul of the University of Massachusetts in Boston and Professor Hamish Spencer of the University of Otago in Dunedin, New Zealand. Although first-cousin marriages are legal in Britain, there have been calls to ban the practice because of reports that it has resulted in a higher-than-average incidence of birth defects in certain immigrant communities where it is common and culturally acceptable. However, Professors Paul and Spencer said that the risk of congenital defects is about 2 per cent higher than average for babies born to first-cousin marriages — with the infant mortality about 4. First-cousin marriages were once quite common in Europe, especially among the elite — Charles Darwin married his first cousin Emma Wedgwood — but that changed in the late 19th-century as people, especially women, became more socially mobile and the risks became more evident. The stigma attached to first-cousin marriages was supported by early studies into human genetics suggesting that “recessive” versions of a gene which are not expressed unless there are two of them, one from each parent are more likely to be expressed in the children of genetically related parents, as well as more likely to be defective. Most states in America have either outlawed or restricted the practice, as has China, Taiwan and both North and South Korea. Professor Spencer, an evolutionary zoologist, said these laws should be repealed, especially in America, where he said they were drafted in a way that discriminated against the rural poor and immigrants: “Neither the scientific nor social assumptions behind such legislation stand up to close scrutiny. Such legislation reflects outmoded prejudices about immigrants and the rural poor and relies on over-simplified views of heredity.

T his is how my genetics professor started off her workshop class with us, during one of the courses in my postgraduate degree in the UK. The workshop dealt with the challenge of examining a particular genetic disorder — and searching for its probable roots. During the course of the workshop, she offered a range of cases, including a family with six children, four of whom suffered from depression, schizophrenia or hearing problems.

Of the 10 cases she shared with us, five of them were Pakistani patients and all of them came from cousin marriages. In more technical language, these are called consanguineous marriages — unions between individuals that are related to each other as either second cousins or closer. These unions hold the potential to create significant genetic issues in nations such as Pakistan, where a recent study estimated that more than 60 percent of the population carries out such marriages.

The situation has prompted lawmakers there to pass new legislation aimed at forcing related couples to seek genetic screenings to fight the rising incidence of a hereditary blood disorder and to raise awareness about the dangers of cousin marriages. Under the Roman civil law , individuals were forbidden to marry anyone within the four degrees.

Because of that, cousin marriages started interchangeably being used with inbreeding or incest and therefore became less common in the west. The same beliefs were not pushed in parts of South Asia and the Middle East, where Islam was the predominant religion and only restricted marriages to the third degree. Thereby cousin marriages not only became a common practice but in time also became a cultural norm that is now actively promoted and preferred in most of those regions.

From a genetics standpoint, the link between these cousin marriages and increased risk of genetic disorders in the offspring of such marriages has become strong. The reason for that is in the laws of probabilities.
