What sort of disease is a congenital abnormality in a baby?

Birth defect: Congenital anomaly is an anatomic abnormality present at birth. There are many conditions that place a baby at risk for having one, but often the cause is unknown.

Various implications: A simple definition would list any abnormal feature in baby found at birth but drs use it specificly for abnormalities of tissue development, reguardless of cause, that distort a body feature or structure. Like a cleft palate. The shrink wrapping tightness of the womb can distort nl tissue & produce a transient change appearance, like a smushed face or twisted foot but this is not considered a ca.

Present from birth: Can affect any organ.Examples: genetic/inherited causes like heophilia, polycstic kidney disease + many rare synromes. Others can be due spontaneous chromasome abnormality like down syndrome: subjects have an extra chromasome + risk increases with advancing maternal age at conception. Can be from an interuterine infection from mother like syphilis. Similarly intrauterine alcohol exposure.
