TUBB4B and isolated hemihyperplasia: DEGs specific to IH included SELE, CASP12, RRAGB, TUBB4B, LIMCH1, IFI6, ANKRD1, CRACR2B, TNFAIP8L3, TMEM140, CASP4LP, SMARCD3, CYREN and TFPI2. Due to low gene count, we could not perform GO BP or KEGG pathway enrichment analysis on the gene set that was significantly altered only under IH.
