How do I know if I have Cloves Syndrome?

CLOVES syndrome is a rare overgrowth disorder characterized by Congenital Lipomatous Overgrowth, Vascular malformations, Epidermal nevi, and Spinal/Skeletal anomalies. Diagnosis is primarily confirmed through clinical evaluation by a specialist and genetic testing to identify a somatic mutation in the PIK3CA gene, which is not inherited from parents but occurs spontaneously after conception.

What are the early signs and symptoms of CLOVES syndrome?

The name CLOVES syndrome serves as an acronym for the primary clinical features. Individuals often present at birth or in early infancy with soft, fatty masses (lipomatous overgrowth), typically on the trunk or limbs. Vascular malformations, such as port-wine stains or venous malformations, are common, alongside epidermal nevi (skin lesions) and specific skeletal variations like large feet or hands (macrodactyly) and spinal curvature (scoliosis).

How is CLOVES syndrome diagnosed?

Diagnosis is a process of clinical observation followed by molecular confirmation. Because CLOVES syndrome is caused by a mosaic PIK3CA mutation, a standard blood test may not always detect it; doctors often prefer to biopsy the affected tissue. Key diagnostic steps include:

• Physical examination by a clinical geneticist or pediatric dermatologist.


• MRI or CT imaging to assess the extent of vascular and fatty tissue involvement.


• Genetic sequencing of affected tissue samples to identify the PIK3CA mutation.


• Orthopedic evaluation to monitor spinal and limb development.

When should I seek urgent medical evaluation?

While CLOVES syndrome is a chronic condition, certain "red flags" require prompt attention. Seek immediate care if you notice rapid, painful enlargement of a fatty mass, sudden onset of severe pain, signs of deep vein thrombosis (DVT) in affected limbs, or neurological changes such as weakness or numbness that could indicate spinal cord involvement.

How can I advocate for myself with medical professionals?

If you suspect you or a loved one has CLOVES syndrome, it is essential to be your own best advocate. Because the condition is rare, many general practitioners may not be familiar with it. When speaking to your doctor, bring printed literature from reputable sources like the NIH GARD or DiseaseMaps.org, where 7 community members have shared their experiences. If your concerns are dismissed, request a referral to a center specializing in vascular anomalies or a pediatric genetics department.

Next steps

• Consult a clinical geneticist or a vascular anomalies specialist.


• Request a referral for genetic testing targeting the PIK3CA pathway.


• Join a patient support community, such as the group at DiseaseMaps.org, to connect with others navigating CLOVES syndrome.
