Furthermore, WNT10A (MIM 6062689) mutations are associated with odontoonychodermal dysplasia (OODD; MIM 257980)[12-14] and mutations in the WNT-associated transcription factors LMX1B (MIM 602575) and MSX1 (MIM 142983) cause Nail-Patella (MIM 161200) and Witkop syndrome (MIM 189500), respectively[15,16]. This evidence concerns the gene MSX1 and odonto-onycho-dermal dysplasia.
