As illustrated in Supplementary Table 3, Degener et al. identified 130 SE events in the frontal lobe of myotonic dystrophy type 1 patients, of which five were also observed in the spinal cord of HSALR mice: Sorbs1 exon 17, Camkk2 exon 16, Dclk1 exon 17, Mmy11 exon 42 and Cacna1g exon 26. Here, SORBS1 is linked to myotonic dystrophy type 1.
