The genes that directly interact with PLLP are involved in cell-to-cell communication and neurological-related diseases, such as the completion and maintenance of myelin sheath (MOG), the ion transporter (SLC31A2) (Schweigel-Röntgen, 2014), and Parkinson’s disease (DBNDD2) (Kim et al., 2006). The gene discussed is DBNDD2; the disease is Parkinson disease.
