Term Description

The interpretation (e.g. not detected, increased risk) of chromosomal microdeletions present in fetal cell-free DNA from maternal plasma. This term was created for, but not limited in use to, QNatal Advanced, a non-invasive prenatal test which uses massively parallel sequencing to identify microdeletions in select chromosome regions, including 22q (DiGeorge syndrome), 15q (Prader-Willi/Angelman syndromes), 11q (Jacobsen syndrome), 8q (Langer-Giedion syndrome), 5p (Cri-du-chat syndrome), 4p (Wolf-Hirschhorn syndrome), and 1p36 deletion syndrome.

Part Description

LP150045-5   Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977. PMID: 271968 Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost. PMID: 18576944 Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template. PMID: 20858600 Source: Regenstrief LOINC
