The real draw of NIPT is its potential as an alternative to invasive testing, a way to replace a needle in the belly with one in the arm, to get information without putting pregnancies in harm's way. Identifying genes on each chromosome is an active area of genetic research. Fig. I received my results from my NIPT and it showed negative for each chromosome 21, 18, 13 - but then it said This specimen showed an expected representation of, chromosome 21, 18 and 13 material.

A genetic rearrangement (translocation) involving chromosome 21 is associated with a type of blood cancer known as core binding factor acute myeloid leukemia (CBF-AML). This change in gene activity blocks the maturation (differentiation) of blood cells and leads to the production of abnormal, immature white blood cells called myeloid blasts. However, the significance of this difference was dependent on which outgroup was used to standardize diversity levels. The following chromosomal conditions are associated with changes in the structure or number of copies of chromosome 21. That's what makes it a gift. A Group Owner is a member that has initiated the creation of a group to connect with other members to share their journey through the same pregnancy & baby stages.

Group Leaders arent expected to spend any additional time in the community, and are not held to a set schedule. The translocation, written as t(8;21), fuses part of the RUNX1 gene from chromosome 21 with part of the RUNX1T1 gene (also known as ETO) from chromosome 8. I assume it is the trisomy.

The American College of Medical Genetics was concerned enough that they proposed a new acronym -- "NIPS" (non-invasive prenatal screening) since the word "screening" implies that further testing is needed to confirm a diagnosis -- that NIPS (or NIPT) is better understood as a first step. I would probably have done the same as you and try to analyze it, I think this is "lab speak" for your results.
