Mr Streeting commended Nelson for challenging the current system and pledged to review SMA screening and the broader use of genomic medicine within the NHS.
Nelson highlighted that a simple heel prick test at birth can detect SMA1 in other countries, allowing for early intervention that can significantly alter a child's prognosis.
Newborn screening for SMA is not routinely available in the UK, though Scotland is set to introduce it, despite advancements in treatment and advocacy from groups like Muscular Dystrophy UK.
