Significant differences in the number of some primary missing teeth (incisor and canine) related to EDA-EDAR genes defects were detected for the first time between XLHED and autosomal recessive HED, suggesting differential local effects of EDA-EDAR genes during odontogenesis.
The impact of WNT10A variants on dental development increases with presence of the nonsense c.(321C>A p.(C107*)) variant and the number of missing teeth.
Recent insights into the role of Wnt10A in tooth development, and the finding of hypodontia in carriers of the autosomal recessive disorder, odontooncychodermal dysplasia, due to mutations in WNT10A (OMIM 257980; OODD), make WNT10A an interesting candidate gene for dental agenesis.
Individuals with a c.1072C > T mutation in the EDAR-gene displayed a typical pattern of congenitally missing teeth in the frontal area with functional consequences.
