To investigate the generality of the MNAT1 cryptic exon, we utilized previously published short-read RNA-seq datasets12,15 from in vitro models that induce TDP-43 loss of function in four cell types: iPSC-derived motor neurons, iPSC-derived cortical neurons, and two neuroblastoma cell lines, SK-N-BE(2) and SH-SY5Y. The gene discussed is MNAT1; the disease is neuroblastoma.
