KCNJ10 and autism: In addition, we have identifiedF8A3, CNTN6, RPE65, and COL19A1 not previously reported in the literatureto have differential expression levels in three sample types in RTT.Although the exact function of F8A3 is not known, it has been linkedto autism and various cancer types, especially in neuroblastoma.40,41 CNTN6, which is involved in sensor-motor neuronal pathways in neurodevelopmentaldiseases, is reported in the gene list associated with RTT-like syndromestogether with KCNJ10.42,43 Apart from these findings, wedetermined that F8A3 and CNTN6 generally displayed the same GO termsas MECP2.
