Fig. 1From: Genomic analysis of a spinal muscular atrophy (SMA) discordant family identifies a novel mutation in TLL2, an activator of growth differentiation factor 8 (myostatin): a case reportReads coverages in SMN exon regions. The four family members were sequenced by WES and the reads were aligned to the exon regions of SMN1 (a) and SMN2 (b). The grey peaks indicate the richness of the reads that mapped to the corresponding exon region in each sample. The red box indicates the alignment coverages of exon 7 of SMN1 and SMN2 in each sampleBack to article page
