What are the latest advances in Cloves Syndrome?

CLOVES syndrome is a rare overgrowth disorder caused by somatic activating mutations in the PIK3CA gene, leading to complex vascular malformations and tissue overgrowth. The most significant advancement in recent years is the transition from symptomatic management to precision medicine using PI3K inhibitors, which target the underlying molecular pathway of CLOVES syndrome.

What is the current state of precision medicine for CLOVES syndrome?

The primary research focus for CLOVES syndrome involves the use of PI3K alpha inhibitors, such as alpelisib. By targeting the overactive PI3K/AKT/mTOR signaling pathway, these therapies aim to reduce the size of vascular malformations and slow the progression of tissue overgrowth. While not a cure, these targeted treatments represent a major paradigm shift in how we manage CLOVES syndrome symptoms.

What are the key research milestones for CLOVES syndrome?

Research into CLOVES syndrome has evolved rapidly, moving from basic genetic discovery to targeted clinical intervention. Key areas of focus include:

• Molecular Diagnosis: The shift toward identifying somatic PIK3CA mutations via deep sequencing of affected tissue rather than blood samples.


• PI3K Inhibitor Trials: Multi-center studies investigating the efficacy of alpelisib in children and adults with PIK3CA-Related Overgrowth Spectrum (PROS), which includes CLOVES syndrome.


• Natural History Studies: Ongoing efforts to map the long-term clinical trajectory of CLOVES syndrome to better inform surgical and medical interventions.

How can patients get involved in clinical research?

Participation in research is vital for understanding CLOVES syndrome. Patients should engage with the following resources to stay updated on trial opportunities:

• Monitor ClinicalTrials.gov by searching specifically for "PIK3CA" or "CLOVES syndrome."


• Connect with the CLOVES Syndrome Community to access patient registries and support networks.


• Consult with specialized centers, such as those within the NIH Undiagnosed Diseases Program or pediatric genetics departments at major academic hospitals.

Next steps

• Consult with a geneticist or a specialist in vascular anomalies to discuss current treatment options.


• Join the DiseaseMaps.org community to connect with other families navigating CLOVES syndrome.


• Review active clinical trials on ClinicalTrials.gov and discuss eligibility with your primary care team.
