LONDON, January 29, 2026 – Former Little Mix singer Jesy Nelson revealed that her twin babies were diagnosed with a rare genetic condition-spinal muscular atrophy type 1 (SMA1)-only after her mother noticed a lack of leg movement, despite multiple check-ups with healthcare professionals.
A Mother’s Observation Leads to Crucial Diagnosis
Early detection is vital for effective treatment of spinal muscular atrophy, a condition that can impact a child’s ability to walk.
- Nelson announced her twins’ SMA1 diagnosis earlier this month via Instagram.
- Healthcare visitors failed to identify early signs of the condition during routine check-ups.
- Nelson is advocating for increased awareness of SMA and met with Health Secretary Wes Streeting to discuss the issue.
Nelson, 34, shared her experience on The UK Tonight program, expressing her relief that her mother intervened. “When I took them home, I was very on edge about everything,” she said. “But the one thing I wasn’t taking notice of was the movement of the legs…it took for my mum to spot that sign and that’s really worrying because we had healthcare visitors come a lot and none of them spotted those signs.”
What is spinal muscular atrophy? SMA is a genetic condition that affects the nerves controlling muscles. It can lead to muscle weakness and, in severe cases, difficulty with movement, including walking.

The singer emphasized the importance of vigilance and early intervention. “Thank God for my mum because I dread to think what position I’d be in now if my mum hadn’t had said anything to me…It’s one of those things that
Nelson has been actively raising awareness about SMA, recently meeting with Health Secretary Wes Streeting. She intends to continue using her platform to advocate for the condition, stating, “I won’t stop talking about it on my socials or in the media…I’ve got to stay noisy.”
