Treatment with antifungal therapy resulted in symptom improvement, however he was unable to establish an effective long-term treatment regimen, resulting in debilitating symptoms. He had undergone extensive work-up without identifying a clear underlying etiology, although Candida species were cultured from the prostatic fluid. 100 genes involved in the cellular immune response were sequenced and a missense mutation was identified in the Ras-binding domain of PI3Kγ. PI3Kγ is a crucial signaling element in leukotaxis and other leukocyte functions. We hypothesize that his mutation led to his chronic infections and pelvic pain.en-USBiologyComputational BiologyGenomicsGenome SequencingSequence AnalysisGeneticsGenetic MutationMedicineClinical ImmunologyImmune ResponseInfectious DiseasesBacterial DiseasesChronic Bacterial ProstatitisFungal DiseasesSystemic MycosesJournal Article2014-02-1810.1371/journal.pone.0068118
