Yes: It is a defect present from birth, yes. Would i call it a birth defect, no.

From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
Range of normal: Head sizes come in a variety of sizes, primarily based on genetics. The head growth is also responsive to the growth of what happens inside. If the genes decide the brain & supportive structure will grow large, larger skull size will occur. If the genes can put it all is a smaller package, the skull will be smaller. Size does not determine quality in the package. I would consider it a nl variation. ...Read more

I have a rare heart birth defect called bicuspid aortic disorder. Lately, I have had a ringing sound in my head and a fuzzy kind of feeling in my head. What could it be?
Nope.: Genetic prenatal testing can detect many chromosomal or microscopic dna defects - but it cannot prevent birth defects! 2-4% of all newborns will have a minor or major birth defect and the vast majority of those have unknown genetic underpinnings at this time, although many of us are working to change that. Take Folic Acid 1-5 mg daily to prevent 75-95% of major neural/cardiac fetal anomalies! ...Read moreSee 2 more doctor answers
Yes, but .....: Clinodactyly is a curve of one or more fingers, which is pretty common, especially for the pinkies, and no big deal at all. Technically it's a minor birth defect and usually not a sign of any problem. But sometimes it's one component of a rare genetic syndrome, like wahab syndrome (http://omim.Org/entry/615170) or a more common one, like down syndrome. I have a little clinodactyly myself! ...Read more
