Transcriptional signatures of participant-derived neural progenitor cells and neurons implicate altered Wnt signaling in Phelan McDermid syndrome and autism.

We developed human induced pluripotent stem cell (hiPSC)-based models of PMS by reprogramming peripheral blood samples from individuals with PMS (n=7) and their unaffected siblings (n=6). Overall design: For each participant, up to three hiPSC clones were generated and differentiated into induced neural progenitor cells (hiPSC-NPCs; n=39) and induced forebrain neurons (hiPSC-neurons; n=41). Genome-wide RNA-sequencing was applied to explore transcriptional differences between PMS probands and unaffected siblings.
