PRKN and Huntington disease: Summarizing the data on the transcription of protein-coding HOX genes and genes encoding lncRNAs in NPCs and TDNs, we could note that, in general, cell lines PD2 and PD3 obtained from the PD patients with the mutations in PARK2 had similar activated expression profiles, while in HD NPCs and TDNs HOX, cluster genes were almost completely off or were transcribed at a very low level.
