Transcriptomes from BD and control iPSCs differed little in the undifferentiated state and transcripts from various BD risk genes including ANK3, CACNA1C, NCAN (chondroite sulfate proteoglycan), SYNE1, and ZNF804A (zinc finger protein 804A) were well upregulated in neurons from both groups. Here, NCAN is linked to Behcet disease.
