Figure 3.

Diagram of the Xp21.2 locus on chromosome X containing the dystrophin gene, represented by the light blue highlighted area. The red dots indicate the chromosome position of SNPs with AvHet >0.4, which were targeted through capture‐based DNA library enrichment for non‐invasive prenatal diagnosis of Duchenne and Becker muscular dystrophies. The brown triangles indicate the chromosome position of all 79 exons contained in the dystrophin gene. The light blue crosses indicate the position of the markers routinely used in our laboratory for linkage analysis in Duchenne and Becker muscular dystrophies families
