Anodontia

Anodontia is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

The offspring of an individual with anodontia are obligate carriers (heterozygotes) of the condition.As mentioned above, carriers typically do not show signs and symptoms of the condition. We encourage you to discuss your questions and concerns related to the risks to your children with a genetics professional.

Anodontia is a dental condition characterized by complete absence of teeth. The primary (baby) or permanent (adult) teeth may be involved. Anodontia is extremely rare when present in a pure form (without associated abnormalities). In most cases, the phenomenon is associated with a group of conditions called the ectodermal dysplasias. In these cases, abnormalities are also noted in the hair, nails, and sweat glands. Anodontia is an autosomal recessive condition. A specific gene has not yet been identified. Treatment involves replacement of the teeth with dentures or implants.
