TLDR Mutations in the p63 gene affect skin adhesion, barrier integrity, and hair growth.
This study investigated the impact of p63 gene mutations on gene and protein expression in AEC syndrome skin. Researchers found significant upregulation of 6 genes and downregulation of 69 genes, primarily affecting epidermal adhesion, skin barrier formation, and hair follicle biology. Notable reductions were observed in genes encoding basement membrane proteins (FRAS1, collagen VII), skin barrier proteins (small proline-rich proteins, late cornified envelope protein, hornerin), lipid transporters (ALOX15B), and hair-associated keratins (25, 27, 31, 33B, 34, 35, 81, 85). These findings provided new molecular insights into the AEC syndrome phenotype.
