Chromosome 7 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 7, one copy inherited from each parent, form one of the pairs. Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 5 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 7 likely contains about 1,150 genes.

Genes on chromosome 7 are among the estimated 20,000 to 25,000 total genes in the human genome.

Spatial configuration of the genome is not inherited, but set up during embryogenesis

The architecture of the DNA-protein complexes that make up the genome in each cell nucleus regulates the course of early embryonic development.

New approach to waking up sleeping genes could help people with Prader-Willi syndrome

New funding is enabling Walter and Eliza Hall Institute researchers to develop new approaches to potentially help people with Prader-Willi syndrome, a devastating and incurable genetic condition.

Researchers identify first gene that predisposes to fainting

Fainting is not solely caused by external factors. Your genes also play a part. This has recently been documented by research team from the University of Copenhagen, Statens Serum Institut and Rigshospitalet.

Researchers identify why lymphoma patients may become resistant to specific drug

With more targeted therapies being approved each year for cancer, the development of drug resistance to these agents is a growing concern.

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.
