Other genes were related to BPD-associated outcomes such as retinopathy of prematurity (ROP, e.g., GBP3, FJX1, HIPK2) and hearing loss (e.g., GJB6, TMEM63B) and mitochondrial energy metabolism (e.g., TOMM7, SLC25A26, SLC25A33, PDK1, PKM, MDH1). The gene discussed is PKM; the disease is hearing loss disorder.
