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.

Biostatistics provides clues to understanding autism: an interview with Dr Knut M. Wittkowski, The Rockefeller University

The incidence of autism spectrum disorders has increased sharply since it was first described 60 years ago. Today, ASD affects more than 1% of all children in the U.S. and about half of them develop a life-long disability.

cfDNA testing lowers false positive rates and higher predictive values in general obstetric population

A study in this week's New England Journal of Medicine potentially has significant implications for prenatal testing for major fetal chromosome abnormalities. The study found that in a head-to-head comparison of noninvasive prenatal testing using cell free DNA (cfDNA) to standard screening methods, cfDNA testing (verifi- prenatal test, Illumina, Inc.) significantly reduced the rate of false positive results and had significantly higher positive predictive values for the detection of fetal trisomies 21 and 18.

Researchers identify gene variants that substantially increase risk for schizophrenia

Schizophrenia has long been known to be highly heritable and is present in approximately 1% of the population. Researchers have been following two paths in their pursuit of identifying schizophrenia risk genes.

Pediatric Cancer Genome Project identifies genetic alteration in brain tumor ependymoma

The St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project has identified the most common genetic alteration ever reported in the brain tumor ependymoma and evidence that the alteration drives tumor development. The research appears February 19 as an advanced online publication in the scientific journal Nature.

Deficiency in SNX27 explains learning impairment in Down's syndrome

Scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have identified the precise role of the protein, SNX27, in the pathway leading to memory and learning impairment.

Subtle epigenetic change plays important role in correct segregation of chromosomes

Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a subtle epigenetic change plays an important role in the correct segregation of chromosomes.

Researchers find 'missing' genetic risk in cancer

A new study could help to answer an important riddle in our understanding of genetics: why research to look for the genetic causes of common diseases has failed to explain more than a fraction of the heritable risk of developing them.

Study findings suggest potential targets for treating HCV

The hepatitis C virus (HCV) has a previously unrecognized tactic to outwit antiviral responses and sustain a long-term infection. It also turns out that some people are genetically equipped with a strong countermeasure to the virus' attempt to weaken the attack on it.

Researchers find link between mutations in gene called RAB 24 and inherited neurodegenerative disease

Researchers from North Carolina State University have found a link between a mutation in a gene called RAB 24 and an inherited neurodegenerative disease in Old English sheepdogs and Gordon setters. The findings may help further understanding of neurodegenerative diseases and identify new treatments for both canine and human sufferers.

Study: Noninvasive prenatal testing detects 83.2% of chromosomal abnormalities

In a study to be presented on Feb. 6 at 9 a.m. CST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting-, in New Orleans, researchers will report that noninvasive prenatal testing detected 83.2 percent of chromosomal abnormalities normally picked up by invasive diagnostic testing strategies, such as chorionic villus sampling (CVS) or amniocentesis.

Bristol-Myers Squibb fourth quarter 2013 revenues increase 6% to $4.4 billion

Bristol-Myers Squibb Company today reported results for the fourth quarter and full year of 2013. The fourth quarter was highlighted by the company's announcement to sell its diabetes business as part of the continued evolution of its successful BioPharma strategy to a specialty care model. The company achieved important regulatory milestones in the quarter for Eliquis in the U.S., daclatasvir/asunaprevir in Japan, daclatasvir in Europe and Farxiga in the U.S. In addition, the company provided financial guidance for 2014.
