Others studied a link between haploinsufficiency of STS and neurodevelopmental disorders, including intellectual disability and autism in a girl.22 Her inherited variants include a 39.6 kb duplication impacting EPHA6, a gene implicated in autism (Supplementary Figure S4) and a 76.8 kb duplication impacting SCN3B (Supplementary Figure S5). This evidence concerns the gene SCN3B and neurodevelopmental disorder.
