In addition, NRK (logFC: −1.58127), involved in neuronal projection morphogenesis [41], SYNPO (logFC: −1.08403), a modulator of actin-based shape and motility of dendritic spines, and JAKMPI1 (logFC: 2.379211), microtubule-associated transporter of GABA-B receptor [42] were significantly altered in PD NPCs (Figure 3B). Here, SYNPO is linked to Parkinson disease.
