Previous studies described the functions of miR-155 in vitiligo pathogenesis by targeting melanogenesis-associated genes such as tyrosinase related protein 1 (TYRP1), tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein epsilon (YWHAE), Syndecan Binding Protein (SDCBP), and SRY-Box transcription factor 10 (SOX10), thereby causing their inactivation35. The gene discussed is YWHAE; the disease is vitiligo.
