New study shows hidden genes may underlie autism severity

Scientists at the University of Colorado Anschutz Medical Campus have implicated a largely hidden part of the human genome in the severity of autism symptoms, a discovery that could lead to new insights into the disorder ...

Decoding the human immune system

For the first time ever, researchers are comprehensively sequencing the human immune system, which is billions of times larger than the human genome. In a new study published in Nature from the Human Vaccines Project, scientists ...

Male Y chromosomes not 'genetic wastelands'

When researchers say they have sequenced the human genome, there is a caveat to this statement: a lot of the human genome is sequenced and assembled, but there are regions that are full of repetitive elements, making them ...

Big data provides clues for characterizing immunity in Japanese

Although genes are distributed widely across chromosomes, many genes related to the immune system are clustered together on human chromosome 6 in a segment called the major histocompatibility complex (MHC) region. The density ...

Human genome

The human genome is the genome of Homo sapiens, which is stored on 23 chromosome pairs. Twenty-two of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs. The Human Genome Project (HGP) produced a reference sequence of the euchromatic human genome, which is used worldwide in biomedical sciences.

The haploid human genome contains an estimated 20,000–25,000 protein-coding genes, far fewer than had been expected before its sequencing. In fact, only about 1.5% of the genome codes for proteins, while the rest consists of RNA genes, regulatory sequences, introns and (controversially) "junk" DNA.
