Hi Izabela, my name is Adam Installed, an excellent Geneticists and you may Genetic Counselor carrying the brand new Stanford Family genes and you can Genomics Certificate regarding Stanford University. I additionally support the Harvard Scientific School’s Genetic Ensure that you Sequencing Technical Specialist Certificate. Excite let me answr fully your inquiries and you will concerns. Usually, a human need 23 sets from chromosomes, totaling 46, 50 % of arises from the fresh new mom’s egg and 50 % of comes from brand new father’s spunk. An effective chromosome is actually a pattern which includes the DNA. When you’re a male, there will be XY chromosome, while a woman, you’ll encounter XX, clearly, that is why as to the reasons Multiple X Disorder is also called (47, XXX). Despite the abnormality, it is seemingly popular and you can occurs in from the one in 1,000 girls/feminine. But not, it’s rarely identified while the fewer than ten% ones on the status know he’s got it as really women having trisomy X live regular lives.
Chromosomes step 1-22 are called autosomes as well as consist of recommendations to make a form of various parts of your body, precisely the last pair of chromosome, referred to as sex chromosome, will establish whenever you are a male or a lady

The precision out-of NiPT examination are 99%, and that the chance of getting an incorrect confident declaration is extremely unusual. As the a standard process, or no of the try information come up average or large exposure, we shall following recommend the happy couple to go for an Amniocentesis to choose although should the pregnancy feel went on, of course, the kind of the state, we.age. „When the my child are influenced by such problem, could i alive a regular existence?” and takes on a large role.
