Research & Genetics

Unfortunately, there is no cure for CLOVES. Surgery and other types of medical interventions are the only treatments for CLOVES overgrowth, vascular anomalies and other related medical issues.


New Research Opportunity [6-13-18]

A medical first: CLOVES Syndrome and overgrowth syndromes:remarkable improvement in the health of 19 pediatric and adult patients using a new therapeutic strategy called Alpelisib BYL719. Dr. Guillaume Canaud at the Necker-Enfants Malades Hospital – AP-HP, the Paris Descartes University, Inserm (INEM Institute Necker Enfants Malades – Centre for Molecular Medicine) and his team recently demonstrated the efficacy of a novel medication, a specific inhibitor called BYL719, in a cohort of 19 patients treated at the Necker-Enfants Malades Hospital – AP-HP and suffering from CLOVES Syndrome (Congenital Lipomatous Overgrowth, Vascular Malformation, Epidermal Naevi) or similar disorders.

New Research Opportunity [10/17/17]

This is an open label, Phase 1/2 study of oral ARQ 092 administered to patients at least 6 years of age with overgrowth diseases and vascular anomalies with genetic alterations of the PI3K/AKT pathway.

Boston Children's Hospital - Sirolimus

As of January 2017, there is no open study of a medication to treat CLOVES. There is growing experience using sirolimus to manage some symptoms and complications of CLOVES, based on studies done by Drs. Denise Adams and Cameron Trenor at Boston Children’s Hospital. Sirolimus has been most effective at controlling infections, leaking from lymphatic vesicles, bleeding and enlarging vascular masses. The decision to recommend sirolimus is based on an individual patient’s complications and should be considered with your physician.


NIH Ongoing Research for PIK3ca mutations:

The National Institutes of Health does research testing of patients with all kinds of overgrowth.

Research at Boston Children's Hospital (ongoing)

Dr. Matthew Warman of Boston Children's Hospital are continuing to do research based gene sequencing for people with CLOVES. In addition, Dr. Warman's lab has mouse models with the PIK3ca mutation. The mouse models will allow researchers to learn about these disorders and to test therapies that may prevent, delay or reverse the consequences of the genetic mutation.

July 2014 --- Clinical Genetic Test available via Washington University 

This test must be ordered by a geneticist/physician. This is somatic variant analysis by next-generation sequencing for Segmental Overgrowth, McCune Albright (SOMA) and related syndromes. The test includes concise, expert interpretations by board-certified clinical genomicists and is covered by most insurance.


Segmental Overgrowth Study (Cambridge, UK)

The SOS are a group of scientists and doctors based in Cambridge, United Kingdom and study CLOVES and related conditions featuring overgrowth of one part of the body, and normal growth elsewhere. As part of our research study we are able to screen genes that are known to cause CLOVES and thereby offer a genetic diagnosis.
