Someone I love has Bohring-Opitz Syndrome, a rare and complex neurodevelopmental disorder caused by a change (mutation) in the ASXL1 gene. This change usually happens randomly, though in some rare cases it may be inherited.
๐ We think about 300 people worldwide are currently diagnosed, making Bohring-Opitz Syndrome an ultra-rare disorder. We believe others may be living with Bohring-Opitz Syndrome but remain undiagnosed due to limited access to genetic testing.
๐ Bohring-Opitz Syndrome affects each person differently, with a wide spectrum of abilities and needs. For many families, Bohring-Opitz Syndrome means managing multiple serious medical challenges at once, often without a roadmap.
Common features may include developmental delay, intellectual disability, seizures, sleep apnea, feeding difficulties, cyclic vomiting, recurrent infections, orthopedic concerns, vision problems, and distinct physical features. Children with Bohring-Opitz Syndrome also have an elevated risk for two rare cancers, Wilms tumor and hepatoblastoma, making cancer screening a routine part of care.
The families and caregivers of people with Bohring-Opitz Syndrome navigate extraordinary medical complexity every single day.
๐ The ARRE Foundationโs mission is to make sure no family faces Bohring-Opitz Syndrome alone. Your donation funds the research, resources, and guidance that help families navigate this condition โ and moves us closer to the treatments they deserve.
