Fig. 1: Analysis workflow for SMA carrier identification.
Among the 1492 WGS data, 12 were excluded due to the output displaying “None”. We identified 23 SMA carriers, resulting in a carrier rate of 1.55%. A subset of participants with SMN Caller results was further validated using MLPA. WGS whole-genome sequencing, SMA spinal muscular atrophy, SMN survival motor neuron, CN copy number, MLPA multiplex ligation-dependent probe amplification.
