Activation of low-expression OMIM-N genes in participants' fibroblasts
(A) Expression levels of OMIM-N genes in clinically assessable tissues. Gene expression levels were classified as follows: low (TPM < 1), moderate (TPM ≥ 1 and <10), and high (TPM ≥ 10). Fibroblasts (FB) RNA-seq data from GTEx and UDN participants (n = 77) were used for the assessment.

(C) Functional enrichment analysis of DEGs up-regulated in iNeurons.
(D) Robust expression of neuron-specific genes in iNeurons.
(E–H) Immunofluorescence staining of neuronal makers Tubulin β-III (TUBB3) (F) and MAP2 (G) in iNeurons. Nuclei were stained using DAPI (H). The merged image is shown in (E). Scale bar represents 100 μm.
