The survival analysis of type I SMA patients. a There were two groups of SMA type I patients: (1) patients with NAIP or GTF2H2 deletion, shown as red curve, n = 11; (2) patients without NAIP or GTF2H2 deletion, shown as green curve, n = 30. (b) SMA type I patients were classified into three groups: (1) patients with exon4 and 5 of NAIP deletion, shown as red curve, n = 6; (2) patients with one exon deletion in NAIP or GTF2H2, shown as green curve, n = 5; (3) patients without NAIP or GTF2H2 deletion, shown as blue curve, n = 30. (c) SMA type I patients were classified into three groups: (1) patients’ copy number (CN) of SMN2 = 2, shown as blue curve, n = 19; (2) patients’ copy number (CN) of SMN2 = 3, shown as red curve, n = 16; (3) patients’ copy number (CN) of SMN2 = 4, shown as green curve, n = 6. (d) SMA type II patients were classified into three groups: (1) patients’ copy number (CN) of SMN2 = 2, shown as blue curve, n = 8; (2) patients’ copy number (CN) of SMN2 = 3, shown as red curve, n = 11; (3) patients’ copy number (CN) of SMN2 = 4, shown as green curve, n = 10
