CLOVES Syndrome is a recently described overgrowth syndrome with complex vascular anomalies. CLOVES stands for Congenital, Lipomatous Overgrowth, Vascular malformations, Epidermal nevi and Scoliosis/Skeletal/Spinal anomalies. The syndrome was described independently by Saap et al. and Alomari [1,2]. The syndrome shows no inheritance among families of affected patients.

CLOVES syndrome is rare and very variable; ranging from mild to severe. The common features in most patients allow for proper diagnosis and distinction from other syndromes. The most consistent features of the...

PIK3CA-related overgrowth spectrum (PROS) is an umbrella term for rare syndromes characterized by malformations and tissue overgrowth caused by somatic mutations in the PIK3CA gene. In PROS diseases, malformations are seen in several different tissues such as skin, vasculature, bones, fat and brain tissue depending on the specific disease.

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.

Genetic testing for CLOVES Syndrome/PROS is more complicated than traditional genetic testing.  Many heathcare providers are still unfamiliar with it.
