Sheri Bermejo (ASXL1 Parent Support) was born and raised in Los Angeles, California.  She has a degree in Urban Studies and Planning from the University of California, San Diego, and works full time as a City Planner.  During her college years she studied abroad at the University of Madrid (La Universidad Complutense).  It was in Madrid where she fell in love with her husband, Carlos.  After spending several years living and working in Madrid, Sheri and her husband married and moved back to California in 2003.   They have two girls, Carmen (6 years old) and Eva (3 years old). Through social networks, a nurse at Children’s Hospital of Los Angeles was able to help diagnose Eva with Bohring-Opitz Syndrome.  Sheri was able to learn more about Bohring-Opitz Syndrome (BOS) from corresponding with mothers on the Bohring-Opitz Syndrome Facebook page.  If mothers from around the world didn’t share their experiences, they would have never been able to diagnose Eva.  Sheri continues to share Eva’s story in hopes that it will inspire others to never give up.   She also is a firm believer in family centered care, especially when caring for a chronically ill child.  In April 2013, Sheri presented Eva’s story to a team of physicians at Children’s Hospital Los Angeles at a Palliative Care and Comfort Conference. In her free time, Sheri loves spending time with her family and rediscovering life through the eyes of her children.


Sünne van Gemert-Godbersen (ASXL1 Parent Support) has a master degree in Urban and Regional Planning from “Technische Universität Berlin”, Germany and worked in retail estate fund (marketing). After 10 years Berlin, the love let her moved to The Netherlands. Together with her husband Rob they have four children: Okke is born 2007 and become wings 2013. He has a younger brother (2009) and younger twin brother and sister (2010). Okke was born with Bohring-Opitz Syndrome. “When we got this diagnosis, just three weeks after his birth, we were told that there were less than 20 children in the world with this syndrome that had been documented in scientific articles. Three years later the Radboud Nijmegen Medical Center discovered the gene that was responsible for this disease: de novo mutation in the ASXL1 gene. Our son, Okke, contributed to this study, and this mutation was also found in his DNA. It was because of this discovery that I decided to set up a group on Facebook with the hope that if there are no children with BOS in the Netherlands that maybe there was the possibility to get in touch with other families worldwide. Now, our international parent support group has grown to more than 100 families from all over the world. It is our goal that by spreading and increasing knowledge about  Bohring-Opitz Syndrome, medical professionals, parents and caregivers will provide better medical treatment for all these beautiful children in the future. They deserve it! Okke is no longer living, … but it is through this work that he lives on!”
