New Research Findings Determine that ‘Dark Matter’ DNA Does Useful Work and Opens Door to Develop More Sophisticated Clinical Pathology Laboratory Tests

Researchers at Penn State identified 160,000 ‘transcription initiation machines’ throughout the human genome

DNA “dark matter” may have something in common with comedian Rodney Dangerfield, who liked to say, “I don’t get no respect!” As many pathologists know, for years the human exome that has been the focus of most research. This is the 1% of the human genome that contains the genes that produce proteins and do other useful functions.

Meanwhile, the remaining 99% of the human genome—sometimes called “junk DNA” and generally known as dark matter—got relatively little attention from researchers. But that is changing. At Pennsylvania State University, a research team has discovered that coding and noncoding RNA, or genomic dark matter, originates at the same types of locations along the human genome.
