Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 7, one copy inherited from each parent, form one of the pairs. Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 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 7 likely contains about 1,150 genes.
Genes on chromosome 7 are among the estimated 20,000 to 25,000 total genes in the human genome.
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).
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.
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.
Dasatanib, a medication currently approved as treatment for drug-resistant chronic myeloid leukemia, provided patients with quicker, better responses as a first therapy than the existing front-line drug, according to researchers at The University of Texas MD Anderson Cancer Center.
Scientists have identified a region of DNA that appears to be involved in the development of pre-cancerous bowel growths (polyps) and that may contain a gene involved in the progression of bowel cancer.
Ablexis, LLC, a biotechnology company dedicated to developing an innovative, next-generation platform for antibody drug discovery, announced today that it has completed a $12 million Series A financing. The round was led by Third Rock Ventures and included Pfizer Venture Investments. Proceeds from the financing will be used to continue advancing Ablexis' proprietary AlivaMab Mouse transgenic mouse platform for the discovery of human therapeutic antibodies.
Many tumor cells would not be viable due to aberrant chromosome distribution if they had not developed a special trick. Scientists from the German Cancer Research Center have investigated which genes are responsible for this survival strategy of cancer cells.
Scientists from Singapore, China and USA have identified three new susceptibility genes in a genome-wide association study of nasopharyngeal carcinoma (NPC). The study, led by the Genome Institute of Singapore (GIS), a biomedical research institute of the Agency for Science, Technology and Research (A*STAR), and the Sun Yat-Sen University Cancer Centre, identified genetic risk factors of NPC that advance the understanding of the important role played by host genetic variation in influencing the susceptibility to this cancer.
Writing the latest pages of an anthropological mystery, scientists propose in this month's Archives of Neurology that it is highly possible that Auguste Deter, the first identified Alzheimer disease patient, carried the N141I presenilin-2 mutation—the same one as in present-day U.S. families descended from German emigrants who settled near the river Volga in Russia.
Although congenital heart disease represents the most common major birth defect, scientists have not previously identified the common variation in the genes that give rise to it. Now genetics and cardiology researchers, two of them brothers, have discovered a genetic variant on chromosome 5 that strongly raises the risk of congenital heart disease.
