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.
According to new research clues to Fragile X syndrome may be connected to one single human gene.
The ALS research team at Umea University in Sweden, working with Dutch and Belgian colleagues, has found new connections between mutations in gene DPP6 and contracting the non-hereditary form of ALS. The findings are being published december 16 in Nature Genetics on the Web.
Researchers from Japan's RIKEN SNP Research Center, collaborating with a team at the University of California, San Diego (UCSD), have discovered a new genetic variation that affects a child's risk of getting Kawasaki disease (KD), an illness characterized by acute inflammation of the arteries throughout the body.
The targeted therapy Herceptin helps women with HER2+ type of breast cancer independent of whether patients have extra copies of chromosome 17, home to the HER2 gene which produces the HER2 protein that fuels cancer growth.
When humans began to migrate out of Africa about 100,000 years ago, their skin color gradually changed to adapt to their new environments.
Ireland Cancer Center of University Hospitals Case Medical Center researchers have recently made great strides in stem cell gene therapy research by transferring a new gene to cancer patients, via their own stem cells, with the ultimate goal of being able to use stronger chemotherapy treatment with less severe side effects.
A new drug for chronic myelogenous leukemia works for patients who have developed resistance to frontline therapy and causes fewer side effects than other medications in its class, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports at the 49th annual meeting of the American Society of Hematology.
Updated clinical trial results show that the drug dasatinib (Sprycel) continues to be highly effective in patients with chronic myelogenous leukemia who were unable to tolerate Gleevec or who developed resistance to it, reports a team led by researchers at Dana-Farber Cancer Institute.
Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different.
There is a clear link between GABA - a chemical substance of the central nervous system that inhibits neurons in the brain - and nicotine dependence, according to a study presented at the American College of Neuropsychopharmacology (ACNP) annual meeting.
Oregon Health & Science University Cancer Institute researchers have opened a new window into the roots of chronic myeloid leukemia (CML).
An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer.
Gleevec, the targeted cancer pill that has saved more than 100,000 lives, now is saving more children with a dire leukemia, as well as preventing disease progression with long term use in adults with chronic myeloid leukemia.
Two drugs approved for use as second line therapy for chronic myelogenous leukemia are showing promising results as frontline therapy for newly diagnosed patients in two clinical trials, research teams led by scientists at The University of Texas M. D. Anderson Cancer Center report at the 49th annual meeting of the American Society of Hematology.
Using a new bottom-up approach for rational drug design, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have reengineered the powerful anticancer drug imatinib - best known by its brand name Gleevec - to more specifically target one type of cancer while potentially curbing a rare life-threatening cardiotoxic side effect.
Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone – a form of artificial intelligence called machine learning – was the key to their success.
Mexican Americans make up 66 percent of the U.S. Hispanic population and, when compared to other ethnic groups, show high rates of heavy drinking and alcohol-related problems.
In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery.
The observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's.
Two independent papers in the December 1st issue of G&D detail how human RecQ helicases regulate homologous recombination and protect genome stability.
