[edit] errors?

I have a few concerns about the accuracy of this article.

The first being the suggestion that only skin cells have the error in genetic code causing the syndrome--if this were true, than only the skin would be affected. To have symptoms of other physical attributes & mental retardation there would have to be errors in the genetic code in those areas of the body as well.

Secondly, an amniocentesis involves removing amniotic fluid from around the fetus. This fluid is composed of many different things, one of them being shed epithelial (skin) cells. In fact, it is from these skin cells that most genetic testing from an amniocentesis is done. In fact, the 1st resource cited in this article states that PKS is suggested as a diagnosis if physical deformities are visible on ultrasound OR if indicated by chionic villi sampling or amniocentesis--which suggests that the genetic error is possible to detect from wither of these tests.

I am not an expert on this subject, but have some knowledge about genetic & obstetric tests. If someone has the answer to these concerns or can explain the seeming incongruencies I would greatly appreciate it. I just think that if information is going to be presented to people, it might as well be correct.

See the sources. They say what is said in the article. The likelihood of the skin cells being analyzed is so low that the prenatal tests can almost never see PKS. — Scm83x ^{hook 'em} 00:28, 6 June 2006 (UTC)
