A National Health Service trust in England has placed a job advertisement for a neonatal nurse specialising in care for families where parents are close relatives, a role that has prompted widespread discussion about public health policy, genetics and cultural context.

Manchester University NHS Foundation Trust described the post as an ‘‘exciting new job opportunity’’ aimed at supporting parents in ‘‘close-relative’’ or cousin marriages to make informed reproductive choices and access genetic services in a culturally sensitive way.

The advertisement, which asked for fluency in languages such as Urdu and emphasised valuing diversity, was filled after applications closed but has drawn attention across the country.

The nurse’s responsibilities were outlined as helping families navigate reproductive decision-making, engaging with genetic counsellors and neonatal care teams, and ensuring newborns are monitored for potential health challenges linked to recessive genetic disorders.

Trust officials said the position was not intended to promote close-relative marriage but to provide targeted care where such family structures are relatively common and where genetic literacy and counselling support can assist families in understanding risks.

Consanguineous relationships, particularly first-cousin marriage, are legal in the United Kingdom and more prevalent in certain communities, such as British Pakistani and Bangladeshi populations, where support tailored to cultural contexts has been highlighted as a clinical priority.

The role follows controversy over recent NHS guidance suggesting that concerns about congenital disease in children born to closely related parents may be ‘‘exaggerated’’ and that risks should be balanced against social, emotional and economic considerations.

Critics outside the health service have sharply criticised this framing, warning that an emphasis on cultural sensitivity should not downplay the significantly higher risk of recessive genetic conditions in children born to first cousins compared with unrelated parents.

Supporters of tailored services have argued that culturally competent health care and genetic counselling are important for reducing health disparities and that specialised roles can help families make informed choices rather than avoid discussion altogether.

The debate underscores broader tensions in British public health between respecting cultural diversity, communicating genetic risks, and protecting child health outcomes.
