Fig. S1 16p11.2 homologs are expressed during development and in the brain. (A) RNA expression analysis by RT-PCR. Total embryo RNA was analyzed for expression of 16p11.2 homologs at 2.5 hpf (blastula), 6 hpf (early gastrula), 11 hpf (late gastrula), 18 hpf (mid-somitogenesis), 24 hpf and 48 hpf. Most genes are expressed maternally, at 2.5 hpf, and expression persists zygotically (6 hpf and later). asphd1, doc2a, prrt2 and sez6L2 show zygotic expression only, suggesting that these genes act later in development. tbx24 expression declines sharply by 48 hpf, suggesting a narrow temporal activity window. Further, this gene is not expressed in brain. (8) Spatial expression analysis by whole mount in situ hybridization. Gene expression was analyzed at 24 hpf (see Methods and Table S4). (a-t) dorsal view, (a′-t′) lateral view. All genes except tbx24 were expressed in the brain.
