What is Schaaf-Yang Syndrome?

Schaaf-Yang syndrome (SYS) is a genetic disorder caused by a disruption of the MAGEL2 gene on chromosome 15. Symptoms include joint contractures, feeding difficulties, developmental delays, intellectual disabilities, sleep disturbances, and more.

The disrupted gene causing Schaaf-Yang syndrome is also missing in another, more common genetic disorder, Prader-Willi syndrome (PWS). PWS is caused when MAGEL2 and several additional genes on chromosome 15 are missing or inactivated.

Recently Diagnosed? We're Here to Help.

The first weeks and months after a diagnosis can be one of the hardest things you'll ever face. As parents of children with SYS, we know what it's like, that is why we wrote First Steps: A Parent's Guide to SYS. This guide was written for parents, by parents and contains important information to help guide you through the beginning of this journey!
