Genetic testing for CLOVES Syndrome/PROS is more complicated than traditional genetic testing.  Many healthcare providers are still unfamiliar with what mutations to test for and what samples are needed.

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.

NIH Ongoing Research for PIK3ca mutations:
The National Institutes of Health does research testing of patients with all kinds of overgrowth.
