The strong correlation between WNT3A-containing epitheliocytes and WNT9B-containing connective tissue cells and the correlation between WNT3A-containing epitheliocytes and WNT9B-containing epitheliocytes are similar to the moderate correlations involving WNT3A and WNT9B seen in UCL tissue, and this also could possibly emphasize the significance of WNT3A and WNT9B activity within both types of postnatal cleft lip tissue. The gene discussed is WNT3A; the disease is cleft lip.
