CLOVES syndrome is an ultra-rare genetic condition caused by a spontaneous mutation in the PIK3CA gene during early fetal development. It is not inherited and can lead to abnormal fatty tissue overgrowth, vascular malformations, skin changes, and skeletal abnormalities. Because symptoms vary widely, many children are initially misdiagnosed, delaying appropriate care. Experts emphasize that early recognition of persistent limb asymmetry, unusual birthmarks, or localized swelling can help prevent serious complications such as blood clots, infections, and chronic pain. New targeted therapies, including PI3K inhibitors like alpelisib, are offering promising treatment options by addressing the underlying genetic pathway rather than simply managing symptoms.
