The American College of Medical Genetics and Genomics (ACMG) has released a new Evidence-Based Clinical Practice Guideline (EBG), "Noninvasive prenatal screening for fetal chromosome abnormalities in ...
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome -forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. [1][2 ...
Chromosomes are made of DNA molecules and are found in the nucleus of a cell. There are 23 chromosome pairs in humans. Transporting genetic information from one cell generation to the next is the main function of chromosomes. Several genes on each chromosome code for different proteins. The features of the entire organism are influenced by or determined by these genes.

The spectrum of information that can be obtained by prenatal testing is wide and rapidly increasing. Many mutations, or "abnormalities," are inconsequential, while others are significant. Genetic ...
A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities ...
