Hello Oldman,

I'm wondering about your last addition ...

"Unfortunately most of the data regarding this disorder are from selected family lines."

I'm asking out of ignorance; is the 'unfortunate' nature of this due to there being few examples and, therefore, an incomplete look at the complexity of the disorder; or it is a matter of there are likely more examples that are misdiagnosed and only those cases that present particular previously described symptomologies are likely to be pursued as further examples? One of the reasons why I ask is that there are many other diseases that fall into the 'only described as case studies' category.

Thanks for educating me a bit on this.

most the data regarding the outcomes of the disease follow family lines. this means that they may be more severe cases than would be found when studying the "average" pjs patient. at least 50% of all pjs patients are due to sporadic mutations in their DNA at conception. the outcomes for these patients is less clear, but they will have an increased risk of developing cancer.

Different sourced websites I've found recently present conflicting data on mortality and morbidity rates. I added the eMedicine link data to the page. But another recently updated article, on GeneReviews, lists three or four different sources of mortality/morbidity information, and they all seem to speak of a 'much more favorable' prognosis than the eMedicine article does. If anyone could provide insight or info on the more accurate statistics, that would be great! I'd like to know how long I might live (LOL) Peoplesunionpro 18:27, 10 July 2007 (UTC)


Hi Where does the recommendation for mammography screening come from? It looks entirely wrong to me. Younger women should be examined more frequently than older because cancer growth rate is higher in young age. --Enro2002 (talk) 13:54, 2 February 2011 (UTC)
