Abstract

We report 2 generalized verrucosis (GV) patients homozygous for a novel mutation in the start codon of IL7. Unlike the previous report in which IL-7 deficiency accompanied CD4 T lymphocytopenia, circulating CD4 T cells were not depleted in one of our patients, suggesting a GV pathogenesis other than poor T-cell development.
