Jesy Nelson, the 34-year-old singer and former Little Mix member, has long been an advocate for those affected by spinal muscular atrophy (SMA), a rare and devastating muscle-wasting disease. In a major victory for the SMA community, the NHS has officially announced that they will be rolling out ‘heel prick’ testing for SMA in newborns, with plans to begin the screening across England in October 2026. The new initiative is set to test approximately 400,000 babies each year for this rare disease, offering new hope for families who may otherwise not discover the condition until it’s too late.
This major milestone follows Jesy’s personal and painful experience with SMA. In January 2026, she revealed that her now nine-month-old twin daughters, Ocean and Story, had been diagnosed with SMA Type 1, the most severe form of the disease. SMA Type 1 is a devastating diagnosis for parents to hear, as it typically results in the child being unable to walk and suffering from severe muscle weakness that eventually leads to respiratory failure, often before the age of two.
Despite the heartbreaking news, Jesy has become a fierce advocate for change. Her tireless campaign to raise awareness and push for earlier diagnosis has led to this moment—one that marks a significant win for families affected by SMA. This new SMA screening test will now be available as part of the NHS’s routine newborn screening program, which already tests for ten other conditions such as cystic fibrosis and sickle cell disease.
A Personal Struggle Transformed Into Advocacy
Jesy’s life was forever changed when she and her ex-partner Zion learned that their daughters were diagnosed with SMA Type 1. The diagnosis came too late, and their daughters are now living with the realities of the condition, requiring specialist equipment to help them breathe at night and feeding tubes to ensure they get proper nutrition. Though doctors were initially unsure about whether treatments would be effective in time to prolong their lives, Jesy and Zion made a decision to keep pushing forward and to continue documenting their journey.
Despite facing immense challenges, Jesy remains resolute in her commitment to make a change. The pop star chose to keep filming her Prime Video documentary series after the diagnosis, offering fans and the world a glimpse into her family’s experience navigating the heartbreaking reality of SMA. In a recent Q&A, Jesy shared, “When the girls got their diagnosis, we decided that we wanted to continue filming. As hard as it was, we were like, ‘You know what? There’s a reason you guys are here, and we’ve got to make the best out of this situation.'”
Jesy’s transparency about the emotional rollercoaster of caring for her daughters, coupled with her bravery in continuing to share their story, has not only shed light on the realities of SMA but also fueled the movement for change. She is determined that her experience, though painful, will lead to improvements in how SMA is treated and diagnosed across the UK.
A Historic Shift for SMA Testing
The NHS’s decision to roll out SMA testing marks a historic shift in the treatment and detection of SMA. Prior to this announcement, SMA testing was not a routine part of the newborn screening program in England. Although there were calls for testing to be expanded, the National Screening Committee had initially rejected the idea, citing concerns over the cost and logistical challenges of widespread screening. However, after much pressure from advocates like Jesy and organizations like SMA UK, the health secretary, Wes Streeting, has committed to moving forward with the plan.
In a letter to Jesy Nelson and Giles Lomax, the Chief Executive of SMA UK, Streeting confirmed that the in-service evaluation of SMA screening would begin earlier than originally planned. The initiative will now launch in October 2026 instead of January 2025. “I am pleased to confirm that screening will now start in October this year rather than January 2025 as previously planned,” Streeting wrote in the letter, much to the delight of SMA advocates and families across the UK.
While the announcement is a huge win for Jesy and the SMA community, it also comes with the sobering reality that thousands of families, like Jesy’s, have been affected by late diagnoses of the disease. The hope now is that the earlier screening will ensure that more children are diagnosed while they are still infants, which will allow families to seek early intervention and access to life-saving treatments that could prolong their children’s lives and improve their quality of life.
A Glimmer of Hope for the Future
For Jesy and her daughters, this announcement is a bittersweet victory. While the new testing program provides a glimmer of hope for future families affected by SMA, it is a reminder of the struggles she and her family continue to face. Jesy has been open about the toll SMA has taken on her family. In a previous interview with the Daily Mail, Jesy spoke about the emotional pain of caring for her daughters, particularly the daily procedures and medical treatments they must endure.
“It’s an emotional rollercoaster, and some days are really tough,” Jesy admitted. “Other days are slightly lighter, but no one can truly understand how intense this is unless they’ve lived through it. It’s a daily struggle. It’s a lot more challenging than people realize.”
In the face of all this, Jesy has chosen to focus on the positives. She is hopeful that her daughters, who are receiving treatments that are still in the early stages of clinical trials, will defy the odds and surpass the grim predictions about their future. “I just have to accept it and now try and make the best out of this situation,” she said. “And my girls are the strongest, most resilient babies, and I really believe that they are going to defy all the odds.”
Jesy’s advocacy and the NHS’s decision to roll out SMA testing are a reminder that there is power in sharing our stories, even the most difficult ones. Her journey has inspired so many to join the fight for SMA awareness and, in the process, has changed the lives of many families who will benefit from this early screening.
What is SMA and Why Is This Testing Important?
Spinal muscular atrophy (SMA) is a genetic condition that affects the motor neurons, which are responsible for controlling muscle movement. As a result, individuals with SMA experience progressive muscle weakness, which can severely impair their ability to move, swallow, and breathe. The severity of the disease varies, with SMA Type 1 being the most severe form, typically diagnosed at birth. Without treatment, children with SMA Type 1 usually do not live past the age of two.
There are currently treatments available for SMA, but early diagnosis is crucial in ensuring that children receive the therapies they need to prolong their lives. The addition of SMA screening to the NHS’s newborn testing program is a critical step in improving early detection and access to treatment for families who may not otherwise have known about the condition until it’s too late.
Jesy Nelson’s advocacy has brought much-needed attention to this rare and devastating condition, and her tireless efforts have made a real difference for future generations.
A Legacy of Change
In the face of an unimaginable challenge, Jesy Nelson has turned her grief and pain into a powerful force for good. By sharing her family’s journey and pushing for change, she has ensured that her daughters’ legacy will be one of hope, progress, and life-saving intervention. As SMA screening becomes a routine part of newborn testing in England, it’s clear that Jesy’s unwavering commitment to advocacy will continue to help others in ways she never could have imagined.
This is just the beginning of a new chapter in the fight against SMA, and thanks to the courage of mothers like Jesy, a brighter future is now within reach for families affected by the disease.
