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.
Northwestern Medicine scientists have discovered a new cause of Parkinson's disease -- mutations in a gene called TMEM230. This appears to be the third gene definitively linked to confirmed cases of the common movement disorder.
Pten (short for phosphatase and tensin homolog) is a tumor suppressor that is defective in about 20-25 percent of all patients with cancers. Mayo Clinic researchers now have discovered that Pten safeguards against tumor formation by keeping chromosome numbers intact when a cell splits into two daughter cells.
Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells' ability to proliferate and replace damaged heart tissue.
Cancer researchers in Würzburg, in cooperation with the international Cancer Genome Atlas Research Network, have identified new genetic drivers of adrenal cancer. Würzburg was the center of coordination of the European scientists.
The Ikerbasque researcher Koen Vandenbroeck, who heads the Neurogenomiks laboratory which reports to the Achucarro centre and the UPV/EHU-University of the Basque Country, together with other national and international groups, has shown that a genetic variant in the 5q11 chromosome, which is associated with susceptibility to developing multiple sclerosis, greatly regulates a gene known as ANKRD55. ANKRD55 is a gene with an unknown function.
Johns Hopkins researchers report they have inadvertently found a way to make human muscle cells bearing genetic mutations from people with Duchenne muscular dystrophy (DMD).
In the largest study of DNA samples from service members with Post-Traumatic Stress Disorder (PTSD), researchers have identified genetic mutations that may be associated with an increased risk factor for PTSD.
RESEARCHERS have identified the gene they believe is responsible for the onset of type 2 diabetes, sparking hope for treatments to prevent and possibly reverse the progressive condition.
In a massive analysis of DNA samples from more than 13,000 U.S. soldiers, scientists have identified two statistically significant genetic variants that may be associated with an increased risk of post-traumatic stress disorder (PTSD), an often serious mental illness linked to earlier exposure to a traumatic event, such as combat and an act of violence.
An international team of scientists, including those at the Translational Genomic Research Institute (TGen), have discovered new avenues of potential treatments for a rare and deadly cancer known as Adrenocortical Carcinoma, or ACC.
A new mouse model of a genetically-linked type of autism reveals more about the role of genes in the disorder and the underlying brain changes associated with autism's social and learning problems.
In a typical cancer cell, up to one-quarter of the genome is lost due to large chromosomal deletions, while the concomitant loss of hundreds of genes creates vulnerabilities that are impossible to reveal through the study of individual genes. Prof. Anna Sablina and her team at VIB/KU Leuven optimized a workflow for the generation of cell lines with targeted chromosomal deletions.
The human placenta is an organ unlike any other. During the course of nine months it is formed by the embryo, sustains life and then is shed.
A tension-sensitive "fail safe" protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes, researchers from the University of Washington and the Fred Hutchinson Cancer Research Center report today, May 5, in the journal Cell.
A recent research study at The Hormel Institute, University of Minnesota is providing insight into the regulation of chromosome segregation and the mechanisms used by cells to prevent them from forming tumors.
Sean Sawicki, who has fragile X syndrome, can be hard to understand and doesn't always have the attention span to carry on a sustained conversation. But a novel intervention developed by UC Davis MIND Institute researchers seems to be making a difference.
Cancer development is a complex process involving both genetic and epigenetic changes. Genetic changes in oncogenes and tumor-suppressor genes are generally considered as primary causes, since these genes may directly regulate cellular growth. In addition, it has been found that changes in epigenetic factors, through mutation or altered gene expression, may contribute to cancer development.
In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.
Third-generation tyrosine kinase inhibitor study findings suggest that bosutinib is associated with a low risk of vascular and cardiac events in patients undergoing first-line or subsequent treatment for chronic myeloid leukaemia.
CRISPRainbow, a new technology using CRISPR/Cas9 developed by scientists at UMass Medical School, allows researchers to tag and track up to seven different genomic locations in live cells. This labeling system, details of which were published in Nature Biotechnology, will be an invaluable tool for studying the structure of the genome in real time.
