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.
The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms , including humans , buttresses the argument that there may be rules as to how genes are structured or laid out on chromosomes, said the Baylor College of Medicine senior author of a report that appears online in the Public Library of Science Genetics, an open-access publication.
While new findings from Ohio State University scientists suggest a genetic marker that could help distinguish between chronic pancreatitis and pancreatic cancer and gauge who will do well with cancer treatment, a pharmacologist at the Kimmel Cancer Center at Jefferson in Philadelphia sees the discovery as much more.
Ten genetic variants associated with type 2 diabetes, a disease which impacts more than 170 million people worldwide, have been identified or confirmed by a U.S.-Finnish team led by scientists at the University of Michigan School of Public Health.
In the most comprehensive look at genetic risk factors for type 2 diabetes to date, a U.S.-Finnish team, working in close collaboration with two other groups, has identified at least four new genetic variants associated with increased risk of diabetes and confirmed existence of another six.
Analysis of three genetic mechanisms that cause non-small cell lung cancer might explain why East Asians respond better than other ethnic groups to a certain type of chemotherapy, a team led by UT Southwestern Medical Center researchers has found.

Researchers have localized two new genes that are associated with fever-related seizures that occur in infancy and childhood, according to a study published in the April 24, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.
Crohn's disease is a chronic relapsing inflammatory disorder of the intestinal tract that affects an estimated 0.15% of people in the developed world. Common symptoms include abdominal pain and diarrhea, but the disorder is often associated with debilitating clinical complications.
Team of researchers led by Professor Richard Gordon and Associate Professor Michael Stowasser has found primary aldosteronism (PAL) , a type of high blood pressure that can be cured by surgery , to be ten times more common than was previously suspected.
A new automated test could enable population screening to identify carriers of the gene mutations causing fragile X syndrome (FXS), the most common inherited form of mental retardation, reports a study in the April issue of Genetics in Medicine, published by the American College of Medical Genetics and Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Hodgkin's disease survivors who have greater genetic instability in their white blood cells are two-and-a-half times more likely to develop another type of cancer, researchers from The University of Texas M. D.Anderson Cancer Center report at the American Association for Cancer Research annual meeting in Los Angeles April 14-18.
deCODE genetics has announced the launch of deCODE T2, a novel DNA-based reference laboratory test for the first common and well-validated genetic risk factor for type 2 diabetes (T2D).
A team of scientists have created primitive human sperm in the laboratory by using bone-marrow tissue from male volunteers.
Cornell experts in computational biology and bioinformatics have made key contributions to the analysis of the genome of the rhesus macaque, better known as the rhesus monkey.
The completed DNA sequence of the rhesus macaque ,an Old World monkey, has advanced understanding of primate evolution and will enhance medical research in neuroscience, behavioral biology, reproductive physiology, endocrinology, heart and blood vessel disease and immunodeficiency, said scientists at the Baylor College of Medicine (BCM) Human Genome Sequencing Center who led the effort.
Up to 15 percent of couples of childbearing age struggle with the heartache of infertility.
The two most prevalent forms of genetic mental retardation, Fragile X and Down syndromes, may share a common cause, according to researchers at Stanford University School of Medicine.
A study published in this week's online edition of Environmental Health Perspectives reports that during the past thirty years, the number of male births has decreased each year in the U.S. and Japan.
A study of human lung tumors indicates that lung cancer patients who lack a particular protein may do more poorly than those with normal levels of that same protein.
New genetic markers may be able to predict whether a person is likely to have coronary heart disease (CAD) in the future.
