Using…pluripotent stem cell (iPSC) reprogramming, the researchers turned the tooth cells into nerve cells…They quickly noticed how different these neurons were compared to those from people without Williams syndrome.

The researchers wrote that their “brain-in-a-dish” cellular model of Williams syndrome could also be used to help better understand a variety of brain disorders…The genes deleted in people with Williams syndrome…appear to keep sociability from being too excessive.
[T]he researchers postulated that the gene named FZD9, missing in most people with Williams syndrome, helps to regulate cell death and neural branching.The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis.
