Based on the findings of higher frequency of positive anti-TPO and anti-Tg antibodies in pemphigus patients than controls by meta-analysis, we also detected the levels of anti-TPO and anti-Tg antibodies in 98 Chinese Han ethnic pemphigus patients (66 PV patients and 32 PF patients) and 65 healthy age-, sex-matched healthy controls (Table 2). The gene discussed is TG; the disease is acquired polycythemia vera.
