Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 9, one copy inherited from each parent, form one of the pairs. Chromosome 9 is made up of about 140 million DNA building blocks (base pairs) and represents approximately 4.5 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 9 likely contains between 800 and 1,300 genes.
Genes on chromosome 9 are among the estimated 20,000 to 25,000 total genes in the human genome.
A multidisciplinary research team at Case Western Reserve University led by Gary Landreth, Ph.D., a professor in the School of Medicine's Department of Neurosciences, has uncovered a common genetic pathway for a number of birth defects that affect the development of the heart and head.
A multidisciplinary research team at Case Western Reserve University led by Gary Landreth, Ph.D., a professor in the School of Medicine's Department of Neurosciences, has uncovered a common genetic pathway for a number of birth defects that affect the development of the heart and head. Abnormal development of the jaw, palate, brain and heart are relatively common congenital defects and frequently arise due to genetic errors that affect a key developmental pathway.
Yale researchers have taken the first critical steps in unraveling the mysteries of brain aneurysms, the often fatal rupturing of blood vessels that afflicts 500,000 people worldwide each year and nearly killed Vice President-elect Joseph Biden two decades ago.
Several recent studies have suggested that common gene variations may be responsible for much of the elevated risk of kidney disease in African Americans.
Discussion of a man's background, attitude, and sexual history isn't just the fodder of Sex and The City episodes - in the future, it could also be a way of evaluating his risk of diabetes.
A very difficult-to-treat child leukemia may benefit from the discovery of a small but potent epigenetic change that launches the cancer - but could potentially be reversed relatively easily, preventing cancer-promoting genes from being turned on.
Researchers at Huntsman Cancer Institute (HCI) believe they may be one step closer to understanding how certain forms of colon cancer develop.
Scientists have found the first genetic link to a common childhood brain tumour - reveals research published in Cancer Research.
Pharmacogenomics research and development innovator PharmaGenoma, Inc. and its subsidiary HairDX, LLC, today unveiled the next generation of its genetic screening test for male pattern baldness. The HairDX test is available immediately thru qualified physicians' offices.
A team of British scientists have developed a ground-breaking new test to screen for genetic diseases in unborn children.
Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome.
The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.
When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.
Genetics researchers have identified two novel gene locations that raise the risk of type 1 diabetes. As they continue to reveal pieces of the complicated genetic puzzle for this disease, the researchers expect to improve predictive tests and devise preventive strategies.
Scientists have discovered that 1 in 7 men have a genetic risk for baldness. Researchers at Canada's McGill University and King's College London along with scientists at drug company GlaxoSmithKline have solved the mystery of male pattern baldness but say treating it will require more research.
Researchers at McGill University, King's College London and GlaxoSmithKline Inc. have identified two genetic variants in caucasians that together produce an astounding sevenfold increase the risk of male pattern baldness. Their results will be published Oct. 12 in the journal Nature Genetics.
Scientists at the world-leading Department of Genetics at the University of Leicester - where the revolutionary technique of genetic fingerprinting was invented by Professor Sir Alec Jeffreys- are developing techniques which may one day allow police to work out someone's surname from the DNA alone.
American researchers have created a prenatal blood test which can be used to determine if an unborn baby has Down's syndrome and the new test is safer for the fetus.
Scientists at The University of Nottingham have isolated three important genes involved in the development of a type of childhood brain cancer. The breakthrough is revealed in a study published in the British Journal of Cancer.
Scientists at Johns Hopkins schools of Public Health and Medicine have, for the first time, identified variants in the gene MYH9 that are associated with increased risk for non-diabetic end stage renal disease (ESRD,) which is the near-loss of kidney function leading to either dialysis of transplant. MYH9, located on the 22 chromosome, is the first gene identified for common forms of kidney disease.
