Answer:
Hypoplasia
Explanation:
Congenital hypothyroidism is most often the result of hypoplasia. Hypoplasia is the process of incomplete development of an organ or tissue in the body. Congenital hypothyroidism is insufficient thyroid hormone production in newborn infants. The underdevelopment of thyroid gland, occurs when the fetus is still in the womb and can be seen in everywhere from tooth enamel to the corpus callosum of the brain, heart, ovaries, various muscle groups, and other regions.
Congenital hypothyroidism is most often the result of thyroid dysgenesis or underdevelopment of the hypothyroid gland.
Congenital hypothyroidism can occasionally also be brought on by a problem with how thyroid hormone is made or by a lack of iodine during fetal development.
Genetic changes or other factors that obstruct normal thyroid gland development can lead to thyroid dysgenesis. TSH receptor gene, PAX8 gene, and NKX2-1 gene mutations are a few genetic changes linked to congenital hypothyroidism.
Mothers who do not get enough iodine, pregnant women who are exposed to radiation, and people who are exposed to certain drugs or chemicals are other causes that may cause thyroid dysgenesis.
