de·vel·op·men·tal a·nom·a·ly

an anomaly established during intrauterine life; a congenital anomaly.

developmental anomaly

any congenital defect that results from interference with the normal growth and differentiation of the fetus. Such defects can arise at any stage of embryonic development, vary greatly in type and severity, and are caused by a wide variety of determining factors, including genetic mutations, chromosomal aberrations, teratogenic agents, and environmental factors. Developmental anomalies are classified either according to the organ system affected, such as congenital heart defects, or according to the way in which the defect occurred, such as developmental failure or arrest, failure to atrophy or subdivide, fusion, splitting, incorrect migration, and misplacement. Most developmental defects are apparent at birth, especially any structural malformation, but some, especially those involving the organ systems, do not become evident until days, weeks, or even years later.

lethal anomaly
a defect which is incompatible with life and leads to the natural death or euthanasia on humane grounds of the neonate concerned.
sex-limited anomaly
limited in its occurrence by the sex of the neonate, e.g. cryptorchidism.
sex-linked anomaly
the gene responsible for the defect is located on the X or the Y chromosome, the sex determinative ones.

Patient discussion about developmental anomaly

Q. Is it a birth defect in children? I know about the causes of autism. Is it a birth defect in children?

A. it's not an easy answer i'm afraid...there are congenital differences, but no "birth defect" that we can detect. there's a good pdf file that gives a full explanation about it...i think you'll find it useful:
