Thyroid agenesis (or thyroid dysgenesis) is a cause of congenital hypothyroidism where the thyroid is missing, ectopic, or severely underdeveloped.
It should not be confused with iodine deficiency, or with other forms of congenital hypothyroidism where the thyroid is present but not functioning correctly.
Congenital hypothyroidism caused by thyroid dysgenesis can be associated with PAX8.
