Floating-Harbor syndrome (FHS) is a rare genetic condition characterized by a combination of physical features and developmental delay. It was first described in medical literature in 1973 by Drs. Richard D. Floating and Robert J. Harbor, hence the name of the syndrome. FHS is associated with alterations in a specific gene called SRCAP, which plays a role in normal growth and development.
Individuals with Floating-Harbor syndrome may have a variety of physical characteristics, including a distinct facial appearance with a triangular-shaped face, deep-set eyes, a broad and prominent nose, a long and smooth philtrum, and a thin upper lip.
In addition to the physical features, individuals with Floating-Harbor syndrome may also experience developmental delay, speech and language delays, intellectual disability, and skeletal abnormalities. The severity and combination of symptoms can vary greatly between individuals, even within the same family.
Floating-Harbor syndrome is inherited in an autosomal dominant pattern, which means that an altered (mutated) gene in one of the parents can be passed on to their children. However, the majority of cases occur sporadically, meaning they are not inherited from a parent and result from a new genetic alteration.
Diagnosis of Floating-Harbor syndrome is made based on the presence of characteristic features and confirmed by genetic testing. Genetic testing can identify alterations in the SRCAP gene, providing a definitive diagnosis for affected individuals. Testing for the syndrome is available through specialized genetic testing centers and may require consultation with a genetic counselor.
Although there is no specific treatment for Floating-Harbor syndrome, ongoing medical management and support can help address the individual needs of affected individuals. Early intervention and specialized educational programs can help individuals with developmental delays reach their full potential.
Patients, too, are unhappy with the care they receive during those brief interactions with their doctors. Healthcare communications company West Corporation reported that 25% of patients don’t feel that their provider cares about them as an individual and nearly 20% aren’t convinced their doctor is focused on improving their health – even though 93% of doctors strongly agree that patient satisfaction is important.
More information about Floating-Harbor syndrome, including research articles, patient support resources, and additional references, can be found on numerous scientific databases and online advocacy websites, such as OMIM (Online Mendelian Inheritance in Man), PubMed, and the Genetic and Rare Diseases Information Center.
Learning more about this rare genetic condition can help patients, families, and healthcare providers better understand the causes, symptoms, and potential treatments associated with Floating-Harbor syndrome.
Frequency
Floating-Harbor syndrome is a rare genetic condition with an altered gene called SRCAP. It was first identified in 1973 and since then, only about 100 cases have been reported in the scientific literature. The syndrome is named after the two doctors who first described it: Dr. Richard A. Floating and Dr. Robert J. Harbor.
The exact frequency of Floating-Harbor syndrome is difficult to determine because it is so rare. However, it is believed to affect both males and females equally. Many cases may go undiagnosed or misdiagnosed due to the lack of awareness and limited resources for genetic testing.
Support and advocacy organizations, such as the Floating-Harbor Syndrome Support Group, provide additional information and resources for patients and their families. They offer support, educational materials, and connect families with other individuals affected by the syndrome.
The syndrome is inherited in an autosomal dominant manner, which means that a person with the altered gene has a 50% chance of passing it on to each of their children. However, in some cases, the syndrome can also occur sporadically without any family history of the condition.
Floating-Harbor syndrome is associated with a range of signs and symptoms, including growth delay, intellectual disability, speech abnormalities, distinctive facial features, and skeletal abnormalities. As these features can vary widely from patient to patient, the condition can sometimes be difficult to diagnose.
Genetic testing is the most reliable way to confirm a diagnosis of Floating-Harbor syndrome. Testing can identify alterations in the SRCAP gene, which is responsible for the syndrome. However, it is important to note that not all individuals with the syndrome will have an identifiable alteration in this gene.
Causes
Floating-Harbor syndrome is a rare genetic condition that is typically caused by alterations in the SRCAP gene. This gene provides instructions for making a protein that is important for the normal development and function of the body.
Scientific advances and further testing have identified other rare genes that can also be associated with Floating-Harbor syndrome. Some of these genes include CHD4, CHD7, DNMT3A, MED12, and RAD21. These genes play a role in various biological processes, including gene regulation and protein production.
The exact inheritance pattern of Floating-Harbor syndrome is still not fully understood. In most cases, it appears to be inherited in an autosomal dominant manner, which means that a mutation in one copy of the gene is sufficient to cause the condition. However, in some cases, the syndrome may be caused by de novo mutations, meaning the alteration occurs spontaneously in the affected individual and is not inherited from their parents.
While the precise causes of Floating-Harbor syndrome are still being investigated, research has shown that altered genes involved in the syndrome can lead to developmental delays and characteristic features of the condition.

Floating-Harbor syndrome (FHS) is a rare genetic condition with altered genes associated. It is a dominant condition, meaning that if a person inherits one altered gene, they will have the syndrome. The gene associated with FHS is called SRCAP, which stands for Snf2-Related CREBBP Activator Protein.
The SRCAP gene is responsible for providing instructions for making a protein that plays a role in the development and function of multiple organs and tissues in the body. Alterations in the SRCAP gene can cause various features of Floating-Harbor syndrome, including delayed speech and language development, short stature, skeletal abnormalities, and distinctive facial features.
