OMIM 605039 | ||
Bohring–Opitz syndrome (BOS) is a medical syndrome characterised by characteristic craniofacial appearance, fixed contractures of the upper limbs, abnormal posture, feeding difficulties, intellectual disability, small size at birth, and failure to thrive. Some of these features are shared with other genetic syndromes.
Genetically, de novo truncating mutations in ASXL1 have been shown to account for approximately 50% of Bohring–Opitz syndrome cases.
Bohring-Opitz Syndrome is an extremely rare genetic syndrome. There are fewer than 60 cases in the world. This syndrome is diagnosed by genetic testing and is a mutation in the ASXL1 gene. The leading cause of death is respiratory infections. Children with BOS can have feeding difficulties, recurring respiratory infections, sleep apnea, developmental delay, failure to thrive, abnormal hair density and length, Wilm’s Tumors, brain abnormalities, silent aspiration, and the list goes on.
