Abstract
The TP63 gene is essential for epithelial proliferation, differentiation, and maintenance during embryogenesis. Despite considerable clinical variability, TP63-related symptoms are characterized by ectodermal dysplasia, distal limb malformations, and orofacial clefts. We identified a novel TP63 variant (c.619A > G, p.K207E) in a seven-month-old Chinese patient with orofacial clefts and ectrodactyly but no evident signs of ectodermal dysplasia. This phenotype was rarely reported before. We summarized the presence of the three main TP63-related manifestations in the literature and noted different distributions of CP- and CL/P-related variants regarding p63 structural domains.
