Not a Hereditary Disease
Cretinism is not a hereditary disease.
Explanation
Hereditary diseases are caused by genetic abnormalities or mutations that are passed down from one generation to another. These diseases are transmitted through the DNA of the parents to their children. Some examples of hereditary diseases are cystic fibrosis, thalassemia, and haemophilia.
Cretinism, on the other hand, is not a hereditary disease. It is a condition caused by a lack of thyroid hormone during fetal development or infancy. This condition can result in severe mental and physical retardation if left untreated. However, cretinism is not passed down through genetics.
In conclusion, cretinism is not a hereditary disease, unlike cystic fibrosis, thalassemia, and haemophilia.
