Bristol NHS Trust Engages 3,100 Families in Newborn Genome Sequencing for Rare Conditions

WHO: University Hospitals Bristol and Weston NHS Foundation Trust (UHBW)

WHAT: Participation in the Generation Study to sequence newborn genomes

WHERE: St Michael’s Hospital and Southmead Hospital, Bristol

WHEN: Update published 10 March 2026

WHY: To detect and treat rare genetic conditions shortly after birth

More than 3,100 Generation Study Bristol families are helping clinicians detect rare but treatable genetic conditions at birth.

Impact of the Generation Study Bristol families project

Maternity teams and research midwives across the Bristol NHS Group have reached a significant milestone. They have supported more than 3,100 babies and their families to participate in the Generation Study.

This major national project aims to sequence the genomes of 100,000 newborn babies across the country. By analysing DNA shortly after birth, clinicians can test for over 200 rare conditions.

Many of these conditions may otherwise go undetected until symptoms develop later in childhood. Identifying these issues soon after birth allows families to access specialist support and monitoring much sooner.

Early intervention helps prevent serious long-term health complications and reduces hospital admissions. Clinicians confirm that this proactive approach improves the overall quality of life for affected children.

St Michael’s Hospital made history as the first site in England to recruit families for the study. The Bristol-based hospital began testing and recruitment for the programme in October 2024.

The University Hospitals Bristol and Weston NHS Foundation Trust was formed by a merger in 2020. It serves a diverse population across Bristol, North Somerset, and South Gloucestershire.

Participation in the study involves collecting a small blood sample from the umbilical cord shortly after birth. This method allows for whole genome sequencing without invasive procedures for the newborn.

The project is entirely voluntary for parents. Nationwide, more than 40,000 women have already signed up to take part in the research.

The study is delivered locally at St Michael’s Hospital and Southmead Hospital. It is led by Dr Tracie Miles and Dr Caroline Platt at UHBW alongside Dr Christy Burden at NBT.

Genomics England leads the Generation Study in partnership with NHS England. The programme represents a significant shift toward personalised medicine within the health service.

By screening for a wide range of treatable conditions, the NHS aims to provide a "head start" for children. Families receive results that can guide immediate clinical decisions and long-term care plans.

The success in Bristol highlights the strong collaboration between maternity teams and research specialists. Staff remain committed to offering this opportunity to as many families as possible.

Parents interested in the study can find more information through the official Generation Study website. Local midwives continue to provide guidance to expectant mothers throughout their pregnancy journey.
