Scotland becomes first in UK to test newborns for rare genetic condition

Scotland has begun testing newborn babies for Spinal Muscular Atrophy (SMA), a rare genetic disorder that causes progressive muscle weakness and severely limits life expectancy without treatment. SMA can reduce a child's lifespan to just two years if left untreated, making early detection critical for intervention. The screening program allows doctors to identify affected infants before symptoms appear, enabling early treatment that can dramatically improve outcomes and quality of life. This makes Scotland one of the latest regions to add SMA to its routine newborn screening panel, a development that reflects growing evidence that early detection and treatment are transformative for patients with this condition.
