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.

Researchers reveal how alteration of single nucleotide could initiate fragile X syndrome

Researchers reveal how the alteration of a single nucleotide—the basic building block of DNA—could initiate fragile X syndrome, the most common inherited form of intellectual disability. The study appears in The Journal of Cell Biology.

Study examines national impact of newborn screening test for SCID

Severe combined immunodeficiency (SCID), a potentially life-threatening, but treatable, disorder affecting infants, is twice as common as previously believed, according to a new study that is the first to examine the national impact of this newborn screening test.

Hippo pathway identifies and prevents progression of abnormal cells into cancer

Researchers from Boston University School of Medicine report that a tumor suppressor pathway, called the Hippo pathway, is responsible for sensing abnormal chromosome numbers in cells and triggering cell cycle arrest, thus preventing progression into cancer.

Avillion initiates BOSULIF Phase 3 trial in patients with chronic phase Ph+ CML

Avillion LLP, a co-developer of late-stage pharmaceutical assets, announces that the first patients have been dosed in the United States in a global Phase 3 clinical trial called "BFORE," which is designed to assess the effectiveness and safety of BOSULIF (bosutinib) as a first-line treatment for patients with chronic phase Philadelphia chromosome positive (Ph+) chronic myelogenous leukemia (CML). The first patient was dosed on July 22, 2014.

Scientists identify mechanism by which inherited neurological disease causes muscle weakness in men

Researchers at University of California, San Diego School of Medicine have identified the mechanism by which a rare, inherited neurodegenerative disease causes often crippling muscle weakness in men, in addition to reduced fertility.

Biomarker for head and neck cancers identified

Although mutations in a gene dubbed "the guardian of the genome" are widely recognized as being associated with more aggressive forms of cancer, researchers at the University of California, San Diego School of Medicine have found evidence suggesting that the deleterious health effects of the mutated gene may in large part be due to other genetic abnormalities, at least in squamous cell head and neck cancers.

Researchers identify RNA that modulates action of important gene in process of programmed cell death

Researchers from the University of S-o Paulo (USP) have identified an RNA known as INXS that, although containing no instructions for the production of a protein, modulates the action of an important gene in the process of apoptosis, or programmed cell death.

FDA approves use of Imbruvica to treat patients with chronic lymphocytic leukemia

The U.S. Food and Drug Administration today expanded the approved use of Imbruvica (ibrutinib) to treat patients with chronic lymphocytic leukemia (CLL) who carry a deletion in chromosome 17 (17p deletion), which is associated with poor responses to standard treatment for CLL. Imbruvica received a breakthrough therapy designation for this use.
