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.

Study: Under-connectivity is the underlying cause of brain disorders

Under-connectivity, or too few connections in the brain, is the underlying cause of brain disorders like autism and schizophrenia, according to a recent study from investigators at the George Washington University Institute for Neuroscience.

Sussex scientists discover new genetic defect that causes intellectual disability

Researchers at the University of Sussex have discovered a new genetic defect which causes a form of intellectual disability; a finding that will improve screening programmes and help to end a 'diagnostic odyssey' for families across the globe.

Researchers use genomics to solve a 20-year case study

After 20 years, a patient's family received an answer to a decades-long genetic mystery. Their daughter had two rare disorders, Angelman syndrome and P450scc deficiency, which was detected after researchers found out she had uniparental disomy, two copies of chromosome 15 from one parent and none from another.

MIT scientists reverse some behavioral symptoms of rare neurodevelopmental disorder

Williams Syndrome, a rare neurodevelopmental disorder that affects about one in 10,000 babies born in the United States, produces a range of symptoms including cognitive impairments, cardiovascular problems, and extreme friendliness, or hypersociability.

New gene therapy cures babies with fatal 'Bubble Boy' disease

A new gene therapy created by US researchers appears to have cured eight infant boys born with a rare genetic disorder referred to as “Bubble Boy” disease.

Maternal age has no effect on IVF success, conclude researchers

Researchers have shown that maternal age may not influence the implantation potential of embryos in IVF or the likelihood of miscarriage.

Bacteria use viruses for self-recognition, study reveals

Bacterial cells that normally colonize our guts can distinguish themselves from other bacterial species using what's traditionally considered their enemy--a virus.

Rare gut condition is more predictable from individual's genetic makeup, study finds

Hirschsprung disease - a rare condition where the failure of gut nerves to develop before birth leads to impaired bowel contractions that prevent infants from passing stool - is more predictable from an individual's genetic makeup than previously envisioned.

New resource accelerates use of FISH techniques to study spatial organization of DNA in cells

Researchers at Karolinska Institutet present a publicly available resource that can accelerate the use of so-called FISH techniques for studying how the genome is spatially organised in the cell nucleus.

Research unravels possible factor for female bias in lupus

The autoimmune disease lupus, which can cause fatigue, a facial rash, and joint pain, strikes females far more often than males. Eight-five percent of people with lupus are female, and their second X chromosome seems partly to blame.

Maternal smoking and pre-eclampsia may affect fertility of offspring

Low levels of oxygen in the womb - which can be caused by smoking or conditions such as pre-eclampsia - may cause problems with fertility later in life, a study carried out in rats suggests.

People born with short telomeres found to have short-lived immune system cells

Scientists at Johns Hopkins say they have found that people born with abnormally short chromosome endcaps, or telomeres, have immune system cells that age and die prematurely.

Study finds novel opportunity for treating subgroup of cancer patients with MSI-H tumors

Researchers have identified a protein critical for the survival of a particular type of tumor cell, according to a study published today in eLife.

Research provides opportunities for biological control of insect-borne pathogens

Researchers from INRA, CIRAD, CEA, the University of Montpellier, and Chicago and Vanderbilt Universities in the United States have developed an innovative method for analyzing the genome of the Wolbachia bacterium.

Immune system errors linked to development of childhood leukemia

Genetic mutations that drive the development of a common type of childhood leukemia can be traced back to errors by the immune system during the production of antibodies.

Study: Female birds have longer, healthier lifespan when they have help raising offspring

Female birds age more slowly and live longer when they have help raising their offspring, according to new research from the University of East Anglia.

Chemistry researchers patent new method for making anti-leukemia compounds

Chemistry researchers at Oregon State University have patented a method for making anti-leukemia compounds that until now have only been available via an Asian tree that produces them.

MIT announces creation of the Alana Down Syndrome Center

As part of MIT's continued mission to help build a better world, the Institute announced the creation of the Alana Down Syndrome Center, an innovative new research endeavor, technology development initiative, and fellowship program launched with a $28.6 million gift from Alana Foundation, a nonprofit organization started by Ana Lucia Villela of São Paulo, Brazil.

Researchers determine factors that cause stress development in the human body

In today's life, we often encounter situations when the organism's functions are overstrained, and the action of extreme factors causes the development of a stress response.

Study sheds new light on early development of embryos

By applying gene analysis to individual cells from early mouse embryos, researchers at Karolinska Institutet in Sweden have discovered previously unknown cellular stages of fetal development from fertilized egg to living being. The study is published in the scientific journal Cell Reports.
