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.
In this interview, we speak to Assad Haffar, the Medical and Humanitarian Aid Director at the World Federation of Hemophilia (WFH).
Why do humans spend a third of their lives sleeping? Why do animals sleep? Throughout evolution sleep has remained universal and essential to all organisms with a nervous system, including invertebrates such as flies, worms, and even jellyfish.
As widely-anticipated decisions about COVID-19 vaccine boosters roll out from U.S. agencies today, insights from an independent study underscore why boosters are important for all adults.
Mount Sinai researchers have developed a new model that uses DNA and RNA sequencing data from hundreds of patients to identify specific genes and genetic alterations responsible for never-before-defined subtypes of a blood cancer called multiple myeloma.
When the pro-inflammatory pair, a receptor called CCR2 and its ligand CCL-2, get together, it increases the risk of developing type 1 diabetes, scientists report.
Scientists at Oxford University have identified the gene responsible for doubling the risk of respiratory failure from COVID-19.
A new study focuses on developing a comprehensive platform to decode the effects of sequence variation identified by GWAS.
Japanese researchers identified chromosome aberrations as a new biomarker in predicting an esophageal cancer patient's risk of experiencing severe chemoradiotherapy side effects.
A team from the UNIGE has developed an application that makes it possible to monitor the frequency and intensity of the symptoms of people at risk for psychosis on a daily basis, in order to be able to adapt their medical follow-up and determine the cause of the appearance of symptoms.
Rutgers researchers have linked the genetic disorders Fragile X and SHANK3 deletion syndrome – both linked to autism and health problems – to walking patterns by examining the microscopic movements of those wearing motion-sensored sneakers.
Males and females differ in prevalence, treatment responses, and survival rates for a variety of diseases. For cardiac disease, women almost uniformly fare far worse than men. There are likely many reasons for this, and scientists at the University of North Carolina at Chapel Hill and Princeton University seemed to have found one deep inside cells before we're even born.
A research team led by Dr Karen Wing Yee YUEN, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) formation in the embryos of the model organism Caenorhabditis elegans, a 1-mm long, transparent nematode.
A new study discusses risk factors for the failure of seroconversion following full vaccination with the COVID-19 Pfizer vaccine.
Nationally recognized for his work studying a novel inflammatory disorder known as VEXAS, David B. Beck, MD, PhD, has joined the Division of Rheumatology at NYU Langone.
A devastating genetic disease called CDKL5 deficiency disorder (CDD), which strikes in early childhood, may be significantly treatable even in adulthood, a new study from the Perelman School of Medicine at the University of Pennsylvania suggests.
Researchers in Qatar have unveiled a high-resolution map of the genetic structure of Arab and Middle Eastern populations, providing new insights into human history in the region and ancestral patterns that may help to explain local human traits and disease risks.
Metagenomics often involves sequencing DNA samples that can only be described as "tricky." Such DNA shows high heterogeneity, which can cause interspecies misassemblies.
The National Institutes of Health has awarded grants to researchers in the Perelman School of Medicine at the University of Pennsylvania to support "highly innovative and broadly impactful" biomedical science through the NIH Common Fund's High-Risk, High-Reward Research program. The seven awards total approximately $8.2 million over five years,
The SingHealth Duke-NUS Maternal and Child Health Research Institute was launched at KK Women's and Children's Hospital (KKH) today by Masagos Zulkifli, Singapore's Minister for Social and Family Development and Second Minister for Health.
Biologists at Cold Spring Harbor Laboratory are using a mathematical approach developed in CSHL Assistant Professor David McCandlish's lab to find solutions to a diverse set of biological problems.
