Hello Izabela, i’m called Adam Installed, a great Geneticists and you will Genetic Therapist carrying the new Stanford Genetics and you may Genomics Certificate of Stanford University. In addition contain the Harvard Medical School’s Genetic Make sure Sequencing Technology Expert Certification. Please allow me to answer your concerns and you may concerns. Usually, a human must have 23 sets from chromosomes, totaling 46, 1 / 2 of comes from the newest mom’s egg and 50 % of originates from new dad’s spunk. Good chromosome is actually a design who has our DNA. When you find yourself a masculine, you will see XY chromosome, if you find yourself a lady, you will see XX, as you can see, this is the reason as to the reasons Multiple X Disorder is also named (47, XXX). In spite of the problem, it is seemingly popular and you may takes place in on the one in 1,000 girls/feminine. not, it is rarely detected since less than 10% of those on the status learn they have it most female with trisomy X real time typical lives.

This leads to another part of the question, the accuracy of one’s shot, and you can what you should do 2nd.

Within my medical center, in addition to Karyotyping, we are going to together with select 84 microdeletions (quick DNA mutations) on genes that cause diseases including Pathology Fibrosis, Wilson’s Problem, Cri-du Talk syndromes and you will an such like. The precision off NiPT assessment is mulheres Costa Rica actually 99%, and therefore the opportunity of bringing a false positive declaration is extremely uncommon.
