YBX1 and isolated hemihyperplasia: Although the RIP‐seq and RNA‐seq datasets did not come from the same cell line and can bring discrepancy for the findings, we detected hundreds of genes that were bound by YBX1 and showed significant difference at expression or alternative splicing levels, indicating that YBX1 has profound influence on its bound targets, thus modulating the pathogenesis or development of IH.
