Floating-Harbor syndrome (FHS) is named after the two hospitals that reported the first cases in the 1970s: Boston Floating Hospital and Harbor General Hospital in California. Signs and symptoms of FHS include short stature, skeletal abnormalities, delayed bone age, kidney problems, minor problems with hearing and vision, characteristic facial features, speech and language problems, and mild to moderate intellectual disabilities. Behavioral difficulties that are present in many children tend to improve with age. FHS is caused by a change (mutation) in the SRCAP gene and inheritance is autosomal dominant. The mutation can be inherited from a parent or can occur for the first time in a person with the syndrome. Communication issues and developmental disabilities may be helped with early intervention programs and special education.
