What type of mutation is oligodontia?

Oligodontia Is Caused by Mutation in LTBP3, the Gene Encoding Latent TGF-β
TGF-β
The TGF-β superfamily includes endogenous growth inhibiting proteins; an increase in expression of TGF-β often correlates with the malignancy of many cancers and a defect in the cellular growth inhibition response to TGF-β. Its immunosuppressive functions then come to dominate, contributing to oncogenesis.

Hypodontia refers to the absence of fewer than 6 teeth (not including third molars). Oligodontia refers to the absence of 6 or more teeth (not including third molars). Anodontia is the complete absence of teeth. Hypodontia is more common in the permanent dentition than in the primary dentition.

What causes anodontia?

Anodontia is caused by genetics. It's different from missing teeth due to gum disease, a mouth injury, cavities, or tooth decay. Instead, anodontia is inherited (passed down from parent to child) in what's called an autosomal recessive pattern.

Is hypodontia dominant or recessive?

Hypodontia may be inherited in an autosomal recessive, autosomal dominant, X-linked dominant, or X-linked recessive mode. The most commonly missing permanent teeth are the third molars (20%), second premolars (3.4%), and maxillary lateral incisors (2.2%) (Simons et al. 1993).

Is ectodermal dysplasia and autoimmune disease?

Abstract. A case is reported of hereditary ectodermal dysplasia with corneal involvement associated with polyendocrinopathy and pernicious anaemia. The presence of autoantibodies to various endocrine organs and ocular tissues is confirmed. This suggests that ectodermal dysplasia may be an autoimmune disease.
