However, The Only Way To Provide A Definitive Diagnosis Is To Have A Diagnostic Procedure (Cvs Or Amniocentesis) With Chromosome Testing.
I just got the results of the nipt test and tested positive for xxy. Advanced maternal and paternal age. Often, boys and men with this condition have milder signs and symptoms than others with.
The Three Most Common Sca Variations In Males Are 47,Xxy (Klinefelter Syndrome), 47,Xyy, And 48,Xxyy.
Klinefelter syndrome (ks) (47, xxy) is the most common sex chromosome disorder, with a prevalence of 1 in every 660 newborn males. You are right, the spectrum of symptoms are all over and there is a lot of overwhelming info on the internet. 49,xxxxy), 46,xy/47,xxy mosaicism, or structurally abnormal x chromosomes [14,15].
A False Positive Result Means That Although Nipt Indicates A High Risk Of Xxy, The Baby Does Not Have.
The nipt/cfdna performance caclulator is a tool to quickly and easily understand the positive predictive value of a prenatal test given the condition, maternal age, specificity of the test, and sensitivity of the test. Some boys will even have more than two x chromosomes (xxxy or xxxxy, for example), which increases the risk of severe symptoms and other health concerns. The high risk for malignancy for carriers of several congenital chromosomal abnormalities is discussed.
There Is Still A 1% Chance That The Cvs Result Is A False Positive, So We Will Confirm Again At Birth.
Very low risk of viable aneuploidy: Even though my ppv was only 30%, xxy was confirmed through cvs. When a boy is born with the xxy condition in only some cells, it's called mosaic klinefelter syndrome.
Currently 31 Weeks Pregnant And Received High Risk For Xxy From Nipt Through The Harmony Test.
I went through this not too long ago. We have also opted out of the aminocentesis as we will continue the pregnancy regardless. 1 in 85,000 to 100,000
