HERPUD1 and amelogenesis imperfecta type 1G: The statistical scatter plot of a single gene shows that the expression of HERPUD1 is significantly positively correlated with ARL2BP, AKTIP and DNAJB9 (Fig. 2d-f), which play an important role in regulating the integrity of microtubules, maintaining the cell cycle, maintaining telomere homeostasis, and protecting cells from apoptosis caused by ERS.
