Figure 2From: Molecular characterization and copy number of SMN1, SMN2 and NAIP in Chinese patients with spinal muscular atrophy and unrelated healthy controlsGene structures inferred from MLPA results. (a)NAIP gene lacking exon 5; (b)SMN1 gene lacking exon 7; (c)SMN2 gene lacking exon 7; (d)SMN2 gene lacking exon 1 to exon 7; (e) Hybrid SMN gene in which exon 8 of SMN2 was converted to exon 8 of SMN1; (f) Hybrid SMN gene in which exon 7 of SMN1 was converted to exon 7 of SMN2; (g)NAIP gene lacking exon13; (h) Hybrid SMN gene in which exon 8 of SMN1 was converted to exon 8 of SMN2.Back to article page
