Trait
Thyroid dysgenesis
Thyroid dysgenesis is a descriptive term that should be avoided if more precise information is available. However, the HPO keeps retains this term because it is commonly used in the medical literature. In humans, the process of thyroid morphogenesis occurs from the 3rd to 16th week of gestation. Alterations occurring during this period may result in a thyroid gland that is absent (thyroid agenesis or athyreosis), hypoplastic (thyroid hypoplasia), or located in an unusual position (thyroid ectopy). All these entities are grouped under the term thyroid dysgenesis.

Changes in these genes cause rare conditions in which Thyroid dysgenesis is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
