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.

New study shows why women's natural fertility curve goes up and down

Throughout life, women's natural fertility curve goes up and down, and in a new study led by the University of Copenhagen, researchers have now shown why. The results might have impact on fertility counselling and in the longer term for treatment of infertility.

Researchers identify gene mutation that causes musculoskeletal problems in children

Researchers have identified a gene mutation that causes developmental delay, intellectual disability, behavioral abnormalities and musculoskeletal problems in children. The newly diagnosed condition, called NKAP-related syndrome, arises from mutations in the NKAP gene, which plays a key role in human development.

Findings shed light on molecular reasons for early miscarriage

Researchers at Karolinska Institutet in Sweden have uncovered a chromosome-wide mechanism that keeps the gene expression of sex chromosomes in balance in our cells.

New trial shows improved survival for patients with advanced colorectal BRAF-mutant cancer

A clinical trial has shown that using a combination of three drugs that target a BRAF gene mutation in patients with mCRC effectively boosts overall survival.

Multiple sclerosis genomic map implicates immune cells in disease susceptibility

The International Multiple Sclerosis Genetic Consortium reports the results of its latest study, "Multiple sclerosis genomic map implicates peripheral immune cells and microglia in susceptibility", in the journal Science today: the highly productive collaborative group presents a new milestone in its efforts to understand the genetic basis of multiple sclerosis.

Study: Whole genome sequencing can improve surveillance, control of gastroenteritis

A new study into one of the UK's leading causes of gastroenteritis has shown how whole genome sequencing can improve its surveillance and control of the disease.

Improved mapping of genomes from 1,000 Swedish individuals

In so-called whole genome sequencing, surveys are made of the total genome of an individual. It is still relatively rare in healthcare today, but it occurs at an increasing rate, for example in order to make an accurate diagnosis in the case of a rare disease.

Study uncovers new DNA sequences in Swedish genomes

People - or more specifically just Swedes - are more like chimpanzees than previously known. This is indicated in a genetic mapping of one thousand Swedish individuals, where new DNA sequences that should be included in the reference genome have been identified.

Discovery provides potential therapeutic target for prostate cancers with PTEN mutation

PTEN, a tumor suppressor gene mutated in approximately 20% of primary prostate cancers, and in as many as 50% of androgen deprivation-resistant prostate cancers, relies on another gene, ARID4B, to function.

Faster, cheaper, better: improved gene therapy tool production

The heart of modern therapy is increasingly personalized and targeted at specific cellular or genetic deficits. This requires gene therapy, in many cases. A new study, published on 19 September 2019 in the journal Nature, describes an improved way to produce purified gene carrier viruses called AAVs cheaply and quickly, from the culture medium.

Genetic mutation appears to help people fight off MRSA

Researchers have discovered that people who carry a certain genetic mutation may have a greater chance of fighting off MRSA infections.

Cure for Rett Syndrome a step closer as scientists successfully reactivate 'back-up’ genes

A team headed by Vincent Pasque at his Lab at KU Leuven alongside researchers from the Jean-Christophe Marine lab and the Edith Heard lab have made a significant step towards developing a treatment for Rett syndrome and other X chromosome linked disorders.

Biologists observe how microtubules branch in new directions in animal cells

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.
