Glutathione S-transferase alpha 2 (GSTA2) also exhibited upregulation in the IPF patients, and its expression was associated with the LTR5A TE (chr6|52,748,278|52,749,305|LTR5A:ERVK:LTR) located 783 bp downstream of that gene (Fig. 6a, Supplemental Table 6A). The gene discussed is GSTA2; the disease is idiopathic pulmonary fibrosis.
