Confirming these transcriptomic data, phosphorylated STAT1 was elevated on protein level in the hair follicle and epidermis of biopsies from folliculitis decalvans (FD), frontal fibrosing alopecia (FFA) and LPP patients (Figs. 6D,E and EV5B,C). The gene discussed is STAT1; the disease is Fabry disease.
