Honda et al. [85] utilized their own RNA-seq dataset and additional transcriptomic datasets (PRJNA524323 and PRJNA597342) of corneal endothelium from FECD patients with and without intronic TNR expansion in TCF4 and normal controls to identify the TCF4 isoforms characterizing FECD. The gene discussed is TCF4; the disease is Fuchs endothelial corneal dystrophy.
