Twelve of these genes (RETN, EPHX2, CD27, NOSIP, APOA1BP, TMCO6, KLHL3, B3GALNT1, SLC9A4, PRKCD, ZNF791, and B3GNT2) were also identified as differentially expressed in BPD in an independent study studying BPD markers in PBMCs (15). The gene discussed is B3GALNT1; the disease is bronchopulmonary dysplasia.
