Stxbp1 is a gene that affects brain development and neurotransmitter signaling. This can result in epilepsy, intellectual disability, developmental delays, movement disorders and other difficulties. We have found that not all Stxers are the same even though there are similarities. With that comes a lot of questions about this disorder.. It?s a spectrum with some more complex than others. We are learning new things about it through research and natural history studies, Willow is a part of the STARR Study which is Natural history Study. Your Support helps with these types of research so we can better understand Stxbp1. It also will help drive other research that are currently on going. Thank you to all of Willows Warriors!
