We then assayed activation of the AKT protein in affected tissues, using phosphorylation-specific antibodies on Western blots. We confirmed and extended an observed association, using a custom restriction-enzyme assay to analyze the DNA in 158 samples from 29 patients with the Proteus syndrome. We performed exome sequencing of DNA from biopsy samples obtained from patients with the Proteus syndrome and compared the resultant DNA sequences with those of unaffected tissues obtained from the same patients. It has been hypothesized that the syndrome is caused by somatic mosaicism for a mutation that is lethal in the nonmosaic state. The Proteus syndrome is characterized by the overgrowth of skin, connective tissue, brain, and other tissues.
