A healthy genome is characterized by 23 pairs of chromosomes, and even a small change in this structure — such as an extra copy of a single chromosome — can lead to severe physical impairment.
They are the Robinson Crusoes of the intracellular world -- lone chromosomes, whole and hardy, stranded outside the nucleus where their fellow chromosomes reside.
Aria Diagnostics (formerly Tandem Diagnostics), a molecular diagnostics company, today announced publication of data supporting a directed, non-invasive approach to cell-free DNA (cfDNA) analysis in maternal blood for evaluation of two common fetal trisomies linked to genetic disorders.
