MAPKAP1 and vitiligo: MAPKAP1 (TOR signaling pathway) promotes dark epithelial pigmentation (Liu et al., 2017), GRL101 (rhodopsin signaling pathway) is an ortholog of the pigment dispersing factor (Tanaka et al., 2014), and enolase (glycolysis/gluconeogenesis pathway) is a biomarker of vitiligo, a human pigmentation disorder affecting melanocytes (Hamid et al., 2015).
