This overlapping of phenotypes was also a feature of WNT10A disease-causing variants which were identified in NSTA, HED, odontoonychodermal dysplasia (OODD; OMIM#257980) and Schopf–Schulz–Passarge syndrome (OMIM#224750) [21,22,23]. The gene discussed is WNT10A; the disease is odonto-onycho-dermal dysplasia.
