Analysis of wound healing-associated genes identified 29 genes with low levels in the CAL tissue and 15 of those, including Pdpn (gp38) (fibroblast marker), Timp1 (MMP inhibitor), and Fcer1g (involved in anti-microbial immunity) was significantly different between CAH and CAL (Fig. 6D + E). Here, PDPN is linked to congenital adrenal hyperplasia.
