Disease >> Exome/Target Region Sequencing
Description
Exome sequencing
Exome sequencing is an innovative technique which selectively sequences the coding regions of the human genome. Exome constitutes about 1% of the human genome (~30Mb) and contains the most functionally relevant DNA sequences that are translated into protein. Exome sequencing can be used to identify novel genes associated with rare and common disorders such as Cancer, Diabetes and Obesity.
Target region sequencingTarget region capture means enriching specific chromosomes (e.g., Y chromosome), specific regions (e.g., HLA region,MHC region) or specific genes, by microarray hybridization (NimbleGen Sequence Capture Array) or solution hybridization (Agilent Sure-Select™ system) based on probes designed according to the sequences of interested regions.
