Two parents who are well-versed in the importance of early screening are pushing for change in the NHS as Jesy Nelson opens up about her twins’ spinal muscular atrophy (SMA) diagnosis.
Jesy Nelson revealed today that her twins may never be able to walk despite their heartbreaking diagnosis of spinal muscular atrophy (SMA). Unfortunately, she is not the only mother who has SMA, which, if left untreated, can be fatal in just two years.
Following a challenging pregnancy and an emergency procedure, Jesy, 34, and her partner, Zion Foster, 27, welcomed their daughters Ocean Jade and Story Monroe Nelson-Foster into the world on May 15. Unfortunately, the baby girls’ health problems increased as a result of discovering they were carrying SMA Type 1, a severe form of the disease that eventually destroys the muscles in a person’s body.
Opening up to followers on Instagram, Jesy shared: “When they assessed the girls at Great Ormond Street, we were told they were never going to be able to walk. They would probably never regain their neck strength. They will be disabled. The best thing we can do right now is to get them treatment and hope for the best. Thankfully, the girls have had their treatment, which I’m so grateful for. If they didn’t have it, they would die.”

Messages of support have flooded in for Jesy, including Rosie and Wes, who have shared their own personal experience of raising two children with SMA, with very different outcomes. Taking to their Marley’s Journey, Facebook page, the parents, from Driffield, East Yorkshire, wrote: “Sending so much love and strength to Jesy & her beautiful family with their twin girls’ diagnosis of SMA type 1.”
Marley and Meadow, age five and six months old, are the parents of Rosie and Wes, who spoke to BBC News about their children’s diagnoses in November and stressed the importance of early screening. While young sister Meadow, who was tested at birth, is meeting all of her developmental milestones and has the ability to undergo gene therapy right away, young Marley, who was diagnosed at five months, is unable to walk or talk and needs assistance with breathing.
Rosie said, “Your life turns around the earlier you learn about the newborn SMA.” Marley requires constant care and complex needs. Meadow will hardly need any breathing assistance because she will live a completely normal life.
Rosie and Wes are now supporting a campaign by the charity SMA UK, which wants to add this condition to a blood test that already screens newborns for ten uncommon but severe conditions. SMA screening is currently only performed on babies who already have a brother or sister who are affected by the condition.
An estimated 47 babies in the UK were born with SMA in 2024, according to SMA UK, despite the fact that one in 40 people have the SMA-related gene that can cause it. When Marley was five months old and given the diagnosis of SMA, Rosie and Wes’ world “came “crashing down.” He received a healthy copy of the affected gene with the life-enhancing gene therapy drug Zolgensma at the age of 16 months.
The nervous system may already have suffered irreversibly negative effects, so timing is everything when it comes to this treatment. Rosie blasted the difficulties Marley faces daily, describing how “Marley needs to have respiratory support every day. He is fed via a tube because he can’t swallow orally. At night, he uses a ventilator. He is unable to speak or walk.
The baby girl can roll over like other girls her age, which makes it a different story for her. She received the drug at just a few weeks old. Rosie is aware of how drastically different the two siblings’ lives will be, despite Marley’s enormous leaps in his progress and his physiotherapy and medication. “I think the guilt that eats me and my partner, as well as other SMA families, is enormous,” Rosie said. It gets better if you’ve had a child with SMA.
Back in 2018, the UK National Screening Committee (NSC) recommended against SMA screening for SMA, due to limited evidence of long-term treatment outcomes, as well as cost-effectiveness for the NHS. Over the past few years, however, the NSC has conducted an external review of the decision, on account of “significant developments”, such as new drugs. Going forward, additional evaluation work is scheduled to be carried out within the NHS.
