Babies will be tested for serious genetic condition in major win for Little Mix singer Jesy Nelson

Jesy Nelson has achieved a historic victory in campaigning for all newborn babies to be screened for spinal muscular atrophy (SMA). This rare genetic condition causes progressive muscle wastage. While the change is a major win, the Little Mix singer describes the outcome as bittersweet. This is because her own twins, who were diagnosed with the condition, are currently not great, marking a personal heartache behind the successful public health initiative for newborns.
