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.
An international consortium including Helmholtz Zentrum München and the German Diabetes Center, Düsseldorf has identified 12 new gene variants which impact the individual's risk of developing type 2 diabetes. The study represents a major contribution towards elucidating the complex pathogenesis of this important widespread disease. Nature Genetics has published the findings of this study in its current issue.
Human embryonic stem cells hold great promise for studying and treating disease and for the practice of regenerative medicine. However, more must be learned to ensure the cells that may one day be transplanted into humans are safe.
Researchers from the European Molecular Biology Laboratory in Heidelberg, Germany, and the Max-Planck Institute of Immunobiology Freiburg have identified a novel protein complex that regulates around 4000 genes in the fruit fly Drosophila and likely plays an important role in mammals, too. Published today in Molecular Cell, their findings explain how another regulatory protein can lead a double life.
An international team has obtained the genome sequence of the human body louse (Pediculus humanus humanus), a parasite that feeds on the blood of its host and a vector of pathogens that cause diseases such as epidemic typhus, relapsing fever and trench fever.
Research currently being undertaken at the University of Leicester may identify reasons underlying an increased risk of Abdominal Aortic Aneurysms in men.
Researchers at the University of Utah are making strides in understanding and combating a motor neuron disease known as Spinal Muscular Atrophy. The spinal muscular atrophies are a group of inherited diseases that cause progressive degeneration of motor nerves resulting in muscle weakness.
Researchers at the University of Utah are making strides in understanding and combating a motor neuron disease known as Spinal Muscular Atrophy. The spinal muscular atrophies are a group of inherited diseases that cause progressive degeneration of motor nerves resulting in muscle weakness. The most common form of the disorder, due to the deletion of a critical gene on chromosome 5, is currently the leading cause of inherited infant and child mortality.
The U.S. Food and Drug Administration today approved a new indication for Tasigna (nilotinib) for the treatment of a rare blood cancer when it is first diagnosed. The cancer, called Philadelphia chromosome positive chronic phase chronic myeloid leukemia (Ph+ CP-CML), is a slowly progressing blood and bone marrow disease linked to a genetic abnormality.
Pediatric oncologist John M. Maris, M.D., describes the current state of the science in combating neuroblastoma, the most common solid cancer of early childhood. In his article in the June 10, 2010 New England Journal of Medicine, "Recent Advances in Neuroblastoma," Maris reviews the field's latest research knowledge—much of it based on efforts by Maris and his colleagues at The Children's Hospital of Philadelphia.
Scientists from the University of Leeds have discovered the mechanisms of a protein known to play an active part in the inherited kidney disorder, Dent's disease. The findings provide a new focus for future therapies for the disease, for which there is currently no cure.
Couples considering undergoing assisted reproductive technology (ART) treatment should be informed about the increased risk of congenital malformation posed by the use of ART, the annual conference of the European Society of Human Genetics will hear today (Monday). Dr. G-raldine Viot, a clinical geneticist at the Maternit- Port Royal hospital, Paris, France, will say that she believed that most doctors working in ART clinics in France only told couples about such risks if they were asked specific questions.
Cancer Research UK scientists have discovered cancer-blocking activity for genes carried on chromosome 21 - an extra copy of which is carried by people with Down's syndrome, reveals research published in Nature.
Scientists have pinpointed key changes to the telomeres in the cells of leukaemia patients which could play a crucial role in the earliest stages of the disease, according to research published online in the journal Blood.
An international consortium of researchers from more than 70 universities, including the University of Utah, has reported that a study of nearly 2,300 people supports the growing consensus that autism is caused in part by rare genetic changes called copy number variants (CNVs).

The study, which appears in the journal the Proceedings of the National Academy of Sciences, is also of potential therapeutic significance-it showed that a brief pharmacological treatment is capable of correcting some of these synaptic deficits in mice genetically engineered to model FXS.
A new study pinpoints the genetic changes that enable Tibetans to thrive at altitudes where others get sick.
Hana Biosciences Inc.,, today announced complete data from its pivotal, Phase 2 RALLY clinical trial for Marqibo® (vincristine sulfate liposome injection) for the treatment of relapsed/refractory adult Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL). Results from the RALLY trial demonstrated compelling evidence of single-agent, anti-leukemic activity in an advanced, heavily pre-treated, adult ALL population.
The Prostate Cancer Foundation announced today that researchers at the University of Michigan Comprehensive Cancer Center have discovered the RAF oncogene that drives fatal melanomas may also drive the aggressive forms of prostate cancer in the clinic.
ARIAD Pharmaceuticals, Inc. today announced updated clinical data from an ongoing Phase 1 study of its investigational pan-BCR-ABL inhibitor, AP24534, in patients with resistant and refractory chronic myeloid leukemia (CML). The data confirm strong clinical evidence of hematologic, cytogenetic and molecular anti-leukemia activity of AP24534, a multi-targeted kinase inhibitor, in heavily pretreated patients with CML, including those with the T315I mutation of the target protein, BCR-ABL.
