WebBirtHoggDub syndrome (BHD), also HornsteinBirtHoggDub syndrome, HornsteinKnickenberg syndrome, and fibrofolliculomas with trichodiscomas and acrochordons is a human, adult onset, autosomal dominant genetic disorder caused by the FLCN gene. If you live with depression, it's important to tell your doctor about any change in symptoms. The PTEN hamartoma tumor syndrome (PHTS) is a spectrum of disorders caused by mutations of the PTEN tumor suppressor gene in egg or sperm cells [5] There is no cure at this time, and in its more advanced forms, it is considered a terminal diagnosis with a life expectancy of 3545 years; treatments are surgery and palliative care, although some chemotherapy has been tried with limited success.
