According to the Centers for Disease Control and Prevention (CDC), most birth defects are believed to be caused by a complex mix of factors including genetics, environment, and behaviors, [13] though many birth defects have no known cause. An example of a birth defect is cleft palate, which occurs during the fourth through seventh weeks of ...
The birth defects caused by the drug thalidomide can range from moderate malformation to more severe forms. Possible birth defects include phocomelia , dysmelia , amelia , bone hypoplasticity , and other congenital defects affecting the ear, heart, or internal organs. [ 41 ]
Beckwith–Wiedemann syndrome (/ ˈ b ɛ k ˌ w ɪ θ ˈ v iː d ə. m ə n /; abbreviated BWS) is an overgrowth disorder usually present at birth, characterized by an increased risk of childhood cancer and certain congenital features. A minority (<15%) of cases of BWS are familial, meaning that a close relative may also have BWS, and parents ...
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.

The NCI study provides limited evidence of an increased risk of birth defects in the sons or daughters of women who were exposed prenatally to DES. An increased risk of ovarian cancer in the daughters of women exposed in utero was observed, but it was based on three cases of almost 800, so the finding is considered preliminary and requires ...
The birth defects caused by thalidomide led to the development of greater drug regulation and monitoring in many countries. [9] [11] It was approved in the United States in 1998 for use as a treatment for cancer. [6] It is on the World Health Organization's List of Essential Medicines. [12] It is available as a generic medication. [8] [13]
Genetic disorders are present before birth, and some genetic disorders produce birth defects, but birth defects can also be developmental rather than hereditary. The opposite of a hereditary disease is an acquired disease. Most cancers, although they involve genetic mutations to a small proportion of cells in the body, are acquired diseases.
