Health: Op-ed links cousin marriages to serious genetic disorders in Britain

A British op-ed argues that cousin marriages within British-Pakistani communities are linked to a surge of serious genetic conditions among children, a claim the author says is not only medical but deeply cultural.

Hundreds of children across Britain are living with crippling neurological syndromes that leave them unable to move without a wheelchair and unable to participate in sports their peers take for granted. Some endure blindness, deafness, learning difficulties, or routine failure of vital organs such as the lungs, liver, heart or kidneys, resulting in shortened lifespans spent in and out of hospitals. The author describes these conditions as so rare that they are effectively nameless, underscoring the profound impact on families. She attributes these tragedies to cousin marriages—an entrenched practice in some Pakistani communities—and argues that the health toll stems from genetics rather than pregnancy-related factors like smoking or maternal age. The piece frames the issue as a cultural problem, rooted in deeply held beliefs and widespread illiteracy, and contends that public health discussions in the United Kingdom have been too timid in addressing it.

The author notes that the practice is prevalent within the British Pakistani community and has been associated with higher rates of disorders such as cystic fibrosis and sickle cell disease. To illustrate global variation in consanguinity, the article references a map created by Professor Alan Bittles, an Australian genomics expert, showing rates of cousin marriage around the world. The map underscores how cultural norms shape genetic risk in different regions and diasporas.

Growing up in Pakistan, the author recalls a country where consanguineous marriages are reported to be common—she cites a figure of about 65 percent of marriages in some parts of the country—which she says informs the dynamics within the diaspora in Britain. The piece also recounts a personal anecdote about a relative who challenged the practice; the relative faced ostracism, illustrating how challenging traditional expectations can carry social consequences. The author argues that such ostracism can deter families from seeking information or medical guidance that might prevent or mitigate genetic disorders in offspring.

The op-ed targets the Genomics Education Programme, an NHS body tasked with educating health professionals about genetics. It criticizes the program for appearing to shy away from discussing cousin marriages openly, arguing that treating the topic as culturally sensitive to the point of silence amounts to indifference toward the health and safety of children. The author contends that the stakes are not merely academic; they are about protecting vulnerable families and preventing avoidable suffering. The piece also points to historical framing, noting that laws permitting cousin marriages date back to the reign of Henry VIII, a reference the author uses to question whether long-standing legal allowances should dictate modern health education and policy.

The author acknowledges the sensitivity involved in discussing culturally rooted practices but argues that acknowledging risk and providing accurate information do not equate to stigmatizing communities. Public health advocates say open conversations, along with genetic counseling and accessible testing, can help families make informed decisions without blaming cultural identities. The piece urges health authorities, educators, and community leaders to engage in respectful, evidence-based dialogue that prioritizes the welfare of children while recognizing the social complexities that influence family decisions.

Beyond the specifics of cousin marriages, medical experts note that consanguinity increases the probability of recessive genetic disorders when both parents carry the same deleterious gene variant. While the overall risk to any single pregnancy remains low, the chance rises with closer genetic relatedness, and population-level patterns can amplify the incidence of heritable conditions. Health agencies have long emphasized the value of preconception counseling and newborn screening as tools to detect and manage such conditions early. The debate highlighted by the op-ed reflects broader questions about how best to balance cultural respect with proactive health education in diverse societies.

In the end, the article calls for a nuanced approach: acknowledge the health risks associated with consanguineous marriages, provide clear information and access to genetic services, and foster open, nonjudgmental dialogue involving families, religious and community leaders, and healthcare professionals. Such an approach, the author argues, could reduce preventable suffering while avoiding the stigmatization of communities that are integral to Britain’s social fabric.
