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.
University of Nevada School of Medicine scientists in the Department of Physiology and Cell Biology have discovered insight into the reproductive workings of the male sex chromosome that may have significant implications for male infertility and contraception.
In parallel studies in human and mouse, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss.
A newly discovered gene fusion is highly expressed in a subset of prostate cancers, according to a study by researchers at Weill Cornell Medical College.
The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end.
Multiple, anatomically distinct lung cancer tumors may frequently arise from a single cancer cell, according to a retrospective analysis of patient tumor samples published in the April 7 online issue of the Journal of the National Cancer Institute.
Scientists of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and Charité - University Medical School, Berlin, Germany, in collaboration with researchers from the Klinikum rechts der Isar of Technical University Munich and Christian Albrecht University, Kiel, have identified a gene variant on chromosome 11 that is associated with an increased risk of atopic dermatitis.
A molecular marker used in America to predict whether children with a form of kidney cancer, called Wilms' tumour, are more likely to relapse than other children, could be useful for UK patients.
Being able to accurately predict how a given cancer will respond to chemotherapy would spare patients with non-responsive tumors the burden of undergoing toxic and ultimately unhelpful treatment.
In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are 10 times more susceptible to the disease than males.

The study, published in the journal Nature Genetics, has shown that susceptibility to a series of blood cancers, known as myeloproliferative disorders (MPDs), is linked to a particular area of the patient's DNA, which is prone to developing mutations.
Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are.
Women who maintain a healthy weight and who have lower perceived stress may be less likely to have chromosome changes associated with aging than obese and stressed women, according to a pilot study that was part of the Sister Study.
