Jesy Nelson, former member of the music group Little Mix, is advocating for nationwide newborn screening for spinal muscular atrophy (SMA) as a debate on the issue is set to take place in Westminster. Nelson, whose twin daughters Ocean and Story were recently diagnosed with the rare genetic disorder, has been campaigning to include SMA in the routine newborn heel prick test across England.

The petition Nelson launched last year, which has garnered more than 150,000 signatures, aims to ensure that all newborns are screened for SMA—a condition that causes progressive muscle weakness and respiratory difficulties. The number of endorsements places the petition among the fastest to reach 100,000 signatures in recent history.

While a pilot screening programme is scheduled to begin in October, it is expected to cover only 72% of England. Nelson has voiced concerns regarding this partial rollout, highlighting the potential for a “postcode lottery” where access to early SMA screening depends on a family’s location. She maintains that universal screening is vital to provide every baby with an equal chance of early diagnosis and treatment.

Nelson has called on supporters to contact their Members of Parliament and join her demonstration outside Parliament in London at 5 p.m. on Monday to show solidarity ahead of the debate. She has emphasized the importance of widespread public and parliamentary backing to expedite policy changes.

In an online statement, Nelson reflected emotionally on how early detection through newborn screening could have altered her daughters’ prognosis. She noted that if treatment begins immediately after birth, symptoms of SMA might be undetectable, underscoring the potential impact of newborn screening programmes.

The forthcoming parliamentary debate will provide lawmakers an opportunity to consider expanding SMA screening coverage. Advocates like Nelson stress that early diagnosis is crucial for timely intervention, which can significantly improve health outcomes for affected infants.
