congenital refers to being present at birth.
Anomalies, abnormalities, defects are often used interchangeably. Not all are genetic or familial.
Malformation and deformation mean different things. Malformation is an anomaly due to abnormal formation of a structure. Deformation is a change in a structure due to forces like pressure, eg, in cases of low amniotic fluid.
