Chromosome 4 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 4, one copy inherited from each parent, form one of the pairs. Chromosome 4 spans more than 191 million DNA building blocks (base pairs) and represents more than 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 4 likely contains between 1,300 and 1,600 genes.

Genes on chromosome 4 are among the estimated 20,000 to 25,000 total genes in the human genome.

UCLA investigates high rates of schizophrenia in people with 22q11.2 deletion syndrome

UCLA has joined an international consortium to investigate the high rates of schizophrenia and other neuropsychiatric disorders in those who are affected with Chromosome 22q11.2 deletion syndrome, a disorder caused by the deletion of a small piece of chromosome number 22.

Penn Medicine receives $12M NIHM grant for genetics study that points causes of mental illness

A major international consortium co-led by Penn Medicine has received a $12 million National Institute of Mental Health (NIHM) grant for a large-scale genetics study investigating why patients with chromosome 22q11.2 deletion syndrome have an increased risk of schizophrenia and other psychiatric disorders.

CHOP’s 22q and You Center plays major role in brain and behavior consortium

Genetics experts from The Children's Hospital of Philadelphia (CHOP) are among the top leaders of a major international collaboration researching why patients with chromosome 22q11.2 deletion syndrome have an elevated risk of schizophrenia and other psychiatric illnesses.

Genetic study helps identify obese diabetes patients who are at risk of developing NAFLD

A groundbreaking study of nearly 2,300 extremely obese diabetes patients, led by the Translational Genomics Research Institute, has identified genes associated with unhealthy liver function.

Standoff between a mutated gene and normal counterpart keeps certain cancer cells alive

What keeps leukemia cells alive almost forever, able to continue dividing endlessly and aggressively? New research at the Weizmann Institute suggests that, in around a quarter of all leukemias, the cancer cells rely on an internal "balance of terror" to keep going.

Length of telomere may help determine prostate cancer patient's prognosis

Like the plastic caps at the end of shoelaces, telomeres protect — in their case — the interior-gene containing parts of chromosomes that carry a cell's instructional material. Cancer cells are known to have short telomeres, but just how short they are from cancer cell to cancer cell may be a determining factor in a prostate cancer patient's prognosis, according to a study led by Johns Hopkins scientists.

New imaging technique reveals first 3D pictures of chromosome structure

A new method for visualising chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with.

Researchers identify mutation in ITGA10 gene that causes chondrodysplasia in dog breeds

Professor Hannes Lohi's research group at the University of Helsinki and Folkhälsan Research Center has identified a mutation in ITGA10 gene, causing chondrodysplasia in two dog breeds, the Norwegian Elkhound and the Karelian Bear Dog.

Research finds greater number of 'escaping genes' on X chromosome

Research from the University of Bath has found a greater number of 'escaping genes' on the X chromosome than have been previously detected, with implications for the understanding of mental impairment in humans.

Inherited human herpesvirus 6 affects telomere stability and reactivates

Up to half a million people in Britain today may not know it, but in their genetic material they carry a particular form of herpesvirus 6 inherited from a parent.

Children with 22q11.2 deletion syndrome may often be misdiagnosed to have autism

Children with a genetic disorder called 22q11.2 deletion syndrome, who frequently are believed to also have autism, often may be misidentified because the social impairments associated with their developmental delay may mimic the features of autism, a study by researchers with the UC Davis MIND Institute suggests.

Findings may help explain why some diabetic women prone to develop kidney failure

A genetic variant on chromosome 2 is strongly linked with kidney failure in diabetic women but not in men, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology.

Dartmouth researchers find that protein cyclin A plays important role in cell division process

In a study to be published in the journal Nature, two Dartmouth researchers have found that the protein cyclin A plays an important but previously unknown role in the cell division process, acting as a master controller to ensure the faithful segregation of chromosomes during cell division.

New research explains how DNA strands repair themselves

Researchers have discovered the details of how cells repair breaks in both strands of their DNA, a potentially devastating kind of DNA damage.

Professor to develop DNA sequencing technologies to search for long-range genome interactions

Why do some people develop disease while others with the same genetic mutation don't? For example, the National Cancer Institute estimates that women who inherit a harmful BRCA2 mutation have a 45 percent chance of developing breast cancer by age 70.

Researchers discover inherited gene mutation linked to childhood leukemia

Researchers have discovered the first inherited gene mutation linked exclusively to acute lymphoblastic leukemia occurring in multiple relatives in individual families. The discovery of the PAX5 gene mutation was led by St. Jude Children's Research Hospital and others. The work appears in the current advance online edition of the scientific journal Nature Genetics.

Biologists identify two pathways via which chromosomes are rearranged

Biologists reported today in Nature that they have identified two pathways through which chromosomes are rearranged in mammalian cells. These types of changes are associated with some cancers and inherited disorders in people.

Scientists develop strain of MERS-CoV that can be used as vaccine against disease

Scientists have developed a strain of the Middle East respiratory syndrome coronavirus (MERS-CoV) that could be used as a vaccine against the disease, according to a study to be published in mBio-, the online open-access journal of the American Society for Microbiology.
