==Etymology==
[http://nordan.daynal.org/wiki/index.php?title=English#ca._1100-1500_.09THE_MIDDLE_ENGLISH_PERIOD Middle English], from [[Latin]] defectus lack, from deficere to desert, fail, from de- + facere to do
*Date: [http://www.wikipedia.org/wiki/15th_Century 15th century]
==Definitions==
*1 a : an imperfection that impairs [[worth]] or utility : shortcoming <the grave defects in our foreign [[policy]]>
:b : an imperfection (as a vacancy or an unlike [[atom]]) in a [[crystal]] [[lattice]]
*2 [Latin defectus] : a lack of something [[necessary]] for completeness, adequacy, or [[perfection]] : deficiency <a hearing defect>
==Description==
''Congenital disorder'' involves [[defects]] in or damage to a [[developing]] fetus. It may be the result of [[genetic]] [[Anomaly|abnormalities]], the intrauterine (uterus) [[environment]], errors of morphogenesis, infection, or a chromosomal abnormality. The outcome of the disorder will further depend on [[complex]] [[interactions]] between the pre-natal deficit and the post-natal [[environment]]. [[Animal]] studies indicate that the [[mother]]'s (and possibly the [[father]]'s) diet, vitamin intake, and glucose levels prior to ovulation and [[conception]] have long-term [[effects]] on fetal [[growth]] and adolescent and adult [[disease]].[2] Congenital disorders vary widely in [[causation]] and abnormalities. Any substance that [[causes]] [[birth]] defects is known as a [http://en.wikipedia.org/wiki/Teratogen teratogen].
