Present at birth, whether caused by genetic factors, developmental processes, environmental exposures before birth, or a combination of factors.
A congenital condition may involve the structure or function of an organ or body system. Some congenital conditions are apparent at birth, while others may not become noticeable until later in life.
Congenital does not mean hereditary. A congenital condition can result from genetic changes, but it can also arise from non-genetic developmental factors or causes that are not known.
QUICK FACT
Congenital means present at birth, not necessarily inherited from a parent.
COMMONLY CONFUSED WITH
Hereditary: describing something transmitted genetically from one generation to another.
