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.

Oxford Gene Technology expands portfolio of fluorescence in situ hybridisation probes

Study suggests potential way to predict autism or psychosis risk in children with genetic abnormality

Doctors and researchers have long known that children who are missing about 60 genes on a certain chromosome are at a significantly elevated risk for developing either a disorder on the autism spectrum or psychosis — that is, any mental disorder characterized by delusions and hallucinations, including schizophrenia. But there has been no way to predict which child with the abnormality might be at risk for which disorder.

Bosutinib resistance linked to ABCB1 transporter

Resistance to the tyrosine kinase inhibitor bosutinib may be mediated by overexpression of the efflux transporter ABCB1, scientists suggest.

Rare BCR-ABL fusions highlighted in CML

Chronic myeloid leukaemia patients with rare BCR-ABL fusions may be missed by quantitative polymerase chain reaction, research suggests.

Researchers find way to reverse clotting factor deficiency that triggers hemophilia A

Sufferers of hemophilia live in a perpetual state of stress and anxiety: their joints wear down prematurely and they have bleeding episodes that feel like they will never end. Their bodies lack the ability to make the clotting factor responsible for the coagulation of blood so any cut or bruise can turn into an emergency without immediate treatment.

Study finds mechanism that identifies cause of intellectual disabilities in autism, Rett syndrome

The term intellectual disability covers a large number of clinical entities, some with known cause and others of uncertain origin. For example Down syndrome is due to an extra copy of chromosome 21 and Rett syndrome is in part caused by a mutation in the control switch gene called MeCP2.

BUSM investigators receive MRA's Jackie King Young Investigator Awards

Boston University School of Medicine researchers Neil Joseph Ganem, PhD and Anurag Singh, PhD, each have received the Jackie King Young Investigator Awards from the Melanoma Research Alliance (MRA), the largest private funder of melanoma research. Both serve as assistant professors of pharmacology & experimental therapeutics and medicine.

Study stresses importance of investigating telomeres to improve diagnoses, develop treatments for many diseases

Studying telomeres, the structures that protect the ends of chromosomes, has become a key issue in biology. In recent years, not only has their relation to ageing been confirmed; defective telomeres seem to be linked to more and more illnesses, including many types of cancer.

Noninvasive prenatal screening could detect maternal cancer

A study published today in the Journal of the American Medical Association shows that genetic test results, as revealed by non-invasive prenatal testing for fetal chromosome abnormalities, may detect underlying conditions in the mother, including cancer.

Researchers identify genetic abnormalities that lead to skin SCC

Squamous cell carcinoma (SCC) of the skin is one of the most frequent cancers in humans affecting more than half million new persons every year in the world. The transformation of a normal cell to a cancer cell is caused by an accumulation of genetic abnormalities in the progeny of single cells. The spectrum of genetic anomalies found in a variety of human cancers have been described.

Researchers identify five recurrent fusion genes involved in acute gastritis and cancer

Studying the gastric cancers of 15 Southeast Asian patients, researchers at The Jackson Laboratory, the Genome Institute of Singapore and other institutions identified five recurrent fusion genes, one of which appears to lead to cellular changes involved in acute gastritis and cancer.

Scientists and families to gather in The Woodlands, Texas to build up community around Christianson Syndrome

It takes a committed community to develop effective treatments for a new disease. With that hope, scientists and families will come together in a Houston suburb July 30- Aug. 2 to build up the community around Christianson Syndrome, a genetic intellectual disability disorder, often associated with autistic features, first discovered 16 years ago.

Breakthrough discovery could help young girls suffering from rare form of epilepsy

An international team, led by a University of Adelaide genetics expert, has made a breakthrough discovery which is expected to help thousands of young girls worldwide who are suffering from a rare yet debilitating form of epilepsy.

New imaging technique helps pinpoint significant event that leads to age-related chromosomal errors

When egg cells form with an incorrect number of chromosomes--a problem that increases with age--the result is usually a miscarriage or a genetic disease such as Down syndrome.

Latent CMV infection induces telomere shortening

The telomeres are repetitive DNA sequences at each end of our chromosomes. Studies show that in every cell division, the telomere is shortened. As a result, the telomere limits the cell to a fixed number of divisions and a limited life span. An essential part of human cells they affect how our cells age - as people with longer telomeres live longer lives. Surprisingly, people who are infected with a latent virus, that is, an asymptomatic virus, have shorter telomeres.

New research links mutations in TEX11 gene to some cases of male infertility

In the most severe form of male infertility, men do not make any measurable levels of sperm. This condition, called azoospermia, affects approximately 1 percent of the male population and is responsible for about a sixth of cases of male infertility.
