Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 6, one copy inherited from each parent, form one of the pairs. Chromosome 6 spans about 171 million base pairs (the building blocks of DNA) and represents between 5.5 percent and 6 percent of the total DNA in cells.
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 6 likely contains between 1,100 and 1,600 genes.
Genes on chromosome 6 are among the estimated 20,000 to 25,000 total genes in the human genome.
Scientists have moved a step closer to understanding how our genetic make-up can lead us to develop heart disease and to predicting who is most at risk.
Scientists at deCODE genetics ( NASDAQ:DCGN ) in collaboration with colleagues from Emory University today report the discovery of the first variant in the sequence of the human genome ever linked to risk of Restless Legs Syndrome (RLS) and Periodic Limb Movements (PLMs).
Pediatrics researchers at The Children's Hospital of Philadelphia and McGill University in Montreal have identified a gene variant that raises a child's risk for type 1 diabetes, formerly called juvenile diabetes.
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired.
The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.
Researchers have identified a new gene mutation linked to frontotemporal dementia, according to a study published in the July 10, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.
A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.
Chromosome disorders in sex cells cause infertility, miscarriage and irregular numbers of chromosomes (aneuploidy) in neonates.
A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.
Researchers at the Ontario Institute for Cancer Research and Cancer Care Ontario have successfully identified a specific genetic variation on chromosome 8 that is associated with colorectal cancer.
New treatments for childhood asthma could be in the pipeline following the discovery of a gene associated with the condition.
In a large-scale study conducted with 2,643 children, international researchers with the participation of the Department of Experimental Pneumology of Ruhr-University Bochum (RUB), Germany (Prof. Dr. Albrecht Bufe), have discovered a gene variant that contributes significantly to the risk of childhood asthma.
A gene that is strongly associated with a risk of developing childhood onset asthma was identified by an international team of scientists, whose findings are published in the journal Nature.
Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.
Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.
A protein long known to be involved in protecting a cell from genetic damage has been found to play an even more important role in protecting the cell's offspring.
PLoS ONE has just published a study which defines a gene locus on chromosome 1 that predicts prognosis of brain tumor patients and may even set the basis for the development of more efficient drugs to combat brain cancer.
Scientists in the United States have been able to reverse the effects of autism in specially bred mice.
Researchers at the Picower Institute for Learning and Memory at MIT have, for the first time, reversed symptoms of mental retardation and autism in mice.
Mushrooms might serve as biofactories for the production of various beneficial human drugs, according to plant pathologists who have inserted new genes into mushrooms.
