Fig. 2From: Comprehensive analysis of genomic complexity in the 5’ end coding region of the DMD gene in patients of exons 1–2 duplications based on long-read sequencingGenetic analysis of the DMD gene in Pedigree 2. A and B show the family pedigree and DMD gene analysis results detected by MLPA, affected boy (II1) had a hemizygous duplication variant of exon 2 in the DMD gene, and his mother and sisiter were heterozygous. C shows a critical breakpoint from a screenshot of the integrative genomics viewer (IGV) based on LRS data analysis. D Schematic diagram shows the locations of breakpoints and architectural features of the duplication variants. E is the result of Sanger sequencing verification for the critical breakpoint. The red dashed line indicates the breakpoints and the red single arrow indicates the same critical breakpointBack to article page
