Transcriptomics

The use of high-density microarrays has impacted the measurement of transcript levels to study complex diseases. With the latest development of microarray technology, it is now possible to quantify transcript levels globally and to integrate such data with information relating to disease. Microarrays based transcriptomics enables mapping a critical genomic region for a disease using affected and unaffected individuals and then pinpointing the responsible gene by identifying differentially expressed genes in the critical region.
