This revealed that VGLL3 expression is >3-fold higher in the quadriceps of boys with Duchenne muscular dystrophy compared to healthy quadriceps (Fig. 1C; by contrast, VGLL2 levels are similar between healthy and Duchenne individuals, see Supplementary Data S1A in Haslett et al., 2003). This evidence concerns the gene VGLL2 and Duchenne muscular dystrophy.
