Fig. 2.

Genomic landscape of the novel exon 4′ in Shank2. a UCSC genome browser conservation track (Placental Cons) for regions around exon 4′. Dotted black boxes indicate highly conserved regions. b UCSC DNA methylation tracks. DNA methylation changes are shown as blue or red (near exon 4′) boxes. Red boxes represent the regions near the identified novel exon. Black arrows indicate known exons in the Shank2 transcript. Red arrow indicates exon 4′
