Genes affected
EDA2R (HGNC:17756): (ectodysplasin A2 receptor) The protein encoded by this gene is a type III transmembrane protein of the TNFR (tumor necrosis factor receptor) superfamily, and contains cysteine-rich repeats and a single transmembrane domain. This protein binds to the EDA-A2 isoform of ectodysplasin, which plays an important role in maintenance of hair and teeth. Alternatively spliced transcript variants encodes distinct protein isoforms.

Partial congenital absence of teeth Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingCenter of Excellence in Genomics and Precision Dentistry, Faculty of Dentistry, Chulalongkorn University-A hemizygous frameshift variant EDA2R: c.620del (p.Asn207Thrfs*124) was identified in a patient with oligodontia. This variant was inherited from his unaffected mother. This variant was absent from population databases, including TOPMed, GenomeAsia, and our in-house database of Thai exomes. A frameshift mutation in EDA2R gene was previously reported in patients with with mild symptoms hypohidrotic ectodermal dysplasia (HED) including hypodontia and irregular shaped teeth (Wisniewski and Trzeciak, 2012). This variant was classified as likely pathogenic based on the ACMG Guidelines for variant interpretation and classification. -
