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.
An international team of scientists have discovered two new genetic links that may predispose children to develop autism.
Preliminary findings from the largest genome scan ever completed in the history of autism research are being published in Nature Genetics. University of Pittsburgh researchers with a consortium of scientists from across the world contributed to this landmark research endeavor through the Autism Genome Project.
In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.
A decades-old cancer mystery has been solved by researchers at Cold Spring Harbor Laboratory (CSHL). "We not only found a critical tumor suppressor gene, but have revealed a master switch for a tumor suppressive network that means more targeted and effective cancer therapy in the future," said CSHL Associate Professor Alea Mills, Ph.D.
The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced today.
Wielding a palette of chromosome paints, scientists at the Salk Institute for Biological Studies have taken a step closer to understanding the relationship between aging and cancer by visualizing chromosomes of cells from patients with a heritable premature aging disease known as Werner Syndrome.
Studying mutations that give rise to a rare genetic disease, genetics researchers have identified a novel biological pathway that may have a broader role during human development, potentially in cases of mental retardation and autism.
A new technique that employs RNA, a tiny chemical cousin of DNA, to turn on genes could lead to therapeutics for conditions in which nudging a gene awake would help alleviate disease, researchers at UT Southwestern Medical Center say.
A research team at Wake Forest University Baptist Medical Center and the University of Heidelberg has proven that a gene protects some people with diabetes from developing severe kidney failure or "end-stage renal disease."
In a new and unique study to determine if genes on the Y chromosome are involved in prostate cancer, researchers at Columbia University's Mailman School of Public Health in conjunction with Hebrew University of Jerusalem found that men who had only daughters had a higher risk of prostate cancer than men who had at least one son, thus signifying a possible defect on the father's Y chromosome.
Researchers have found that a class of RNA molecules, previously thought to have no function, may in fact protect sex cells from self-destructing. These findings will be published in the November 17 issue of the journal Cell.
Researchers at the John A. Moran Eye Center at the University of Utah have identified a gene called HTRA1 that contributes to a major risk of Age Related Macular Degeneration (AMD), the most common cause of irreversible vision loss in the developed world.
Researchers supported by the National Institutes of Health report in the current issue of the journal Science that a much-studied gene called SUMO1, when under expressed, can cause cleft lip and palate, one of the world's most common birth defects.
Mayo Clinic virologists have discovered that a specific human protein is essential for HIV to integrate into the human genome.
A discovery at the Barbara Davis Center for Childhood Diabetes has identified a genetic risk for type 1 diabetes three to four times higher than previously thought possible.
Researchers in Boston have discovered a new common, noncoding variant in the Complement Factor H (CFH) gene that is associated with age-related macular degeneration (AMD), the leading cause of irreversible visual impairment and blindness among persons aged 60 and older.
Fred Hutchinson Cancer Research Center, The Netherlands Cancer Institute (NKI) and Cancer Research Technology Limited (CRT) today have released details of the development and commercialisation of a powerful protein-genome interaction mapping technology termed 'DamID.'
The common thinking in the past had been that Rett syndrome only affects girls.
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve.
Embryonic stem cells are derived from embryos that are undergoing a period of intense cellular activity, including the chemical addition of methyl groups to specific DNA sequences in a process known as DNA methylation.
