Of the 86 samples that tested positive , the fraction of mutant DNA in the positive specimens ranged from 1 percent to 47 percent. The mutation-positive specimens included uncultured tissues, which eliminated the hypothesis that the mutation was an artifact of cellular tradition. Of 41 unaffected samples, 13 had been positive for the mutation. DNA that was purified from the peripheral bloodstream of patients with the Proteus syndrome was uniformly negative on Sanger sequencing . Nevertheless, the restriction-enzyme assay showed that two peripheral-bloodstream DNA samples had been positive . Overall, of 29 individuals with the Proteus syndrome who had been tested, 26 carried the mutation, as detected in one or even more samples. Functional Characterization We next evaluated the functional consequence of the mutation, which may constitutively activate AKT1 through Ser473 and Thr308 phosphorylation.11 Cell lines which were cultured from surgical explants from sufferers with the Proteus syndrome showed increased Ser473 phosphorylation under conditions of serum starvation, in comparison with the control samples .
