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 mechanism may prevent the natural aging of immune cells

A new mechanism that slows down and may even prevent the natural aging of immune cells – one of the nine 'hallmarks of aging' – has been identified by an international team led by UCL scientists.

Experimental drug prolongs survival, improves muscle function in mice severe Duchenne muscular dystrophy

Researchers at Johns Hopkins Medicine report that an experimental drug first developed to treat kidney disease prolongs survival and improves muscle function in mice genetically engineered to develop a severe form of Duchenne muscular dystrophy (DMD).

New technology reveals cellular changes across neural-epithelial-vascular complex in choroideremia

By combining traditional eye imaging techniques with adaptive optics - a technology that enhances imaging resolution - researchers at the National Eye Institute have shown for the first time how cells across different tissue layers in the eye are affected in people with choroideremia, a rare genetic disorder that leads to blindness.

Study investigates the efficacy and safety of selpercatinib in a diverse group of patients

The highly selective RET inhibitor selpercatinib was well-tolerated and achieved durable objective responses across multiple tumor types in the Phase I/II LIBRETTO-001 trial, according to researchers from The University of Texas MD Anderson Cancer Center.

Gene variants associated with blood type may contribute to risk of early stroke

Gene variants associated with a person's blood type may be linked to their risk of early stroke, according to a new meta-analysis published in the August 31, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Brain activity patterns during sleep shed light on the neurobiology behind 22q11.2 Deletion Syndrome

The brain activity patterns during sleep shed light on the neurobiology behind a genetic condition called 22q11.2 Deletion Syndrome (22q11.2DS) and could be used as a biomarker to detect the onset of neuropsychiatric disorders in people with 22q11.2DS.

Genetic screening before pregnancy detects the risk in 44% of couples

Are would-be parents carrying a genetic risk of serious illnesses that they could potentially pass on to their children? In the USA, doctors recommend that couples have genetic screening before trying to conceive.

Study addresses food texture challenges in the life of children with Down syndrome

Children with Down syndrome prefer food with a crispy, oily mouthfeel and don't like brittle or gooey foods. But those preferences can lead to a less nutritious diet, according to Washington State University research published in the Journal of Texture Studies.

Facial recognition algorithms show genetic similarities in genetically unrelated look-alike humans

In a new study, researchers identified look-alike humans who were genetically unrelated using facial recognition (FR) algorithms for multi-omics studies.

Simple blood test can accurately detect Alzheimer's disease in people with Down syndrome

Around 80% of people with Down syndrome develop Alzheimer's disease, often when they are between 40 and 50 years old.

Combination of new testing methods helps identify multiple dementia risk genes

A new UCLA-led study has identified multiple new risk genes for Alzheimer's disease and a rare, related brain disorder called progressive supranuclear palsy (PSP) by using a combination of new testing methods allowing for mass screening of genetic variants in a single experiment.

GPNMB established as a risk gene and potential therapeutic target for Parkinson's disease

Computational, cell biological, and human tissue-based studies establish GPNMB as a risk gene and potential therapeutic target for Parkinson's Disease (PD), researchers report.

The eyes of mutant zebrafish help understand the role of a protein in preventing cell death

Around 15 years ago, a group of researchers discovered mutant zebrafish. The eyes of these zebrafish did not develop correctly, resulting in them being significantly smaller than the eyes of wild zebrafish.

Study reveals the effects of an atypical mode of chromosome arrangement on genome architecture and evolution

A research team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, has uncovered the profound effects of an atypical mode of chromosome arrangement on genome organization and evolution.

Fruit fly genome contains whole genomes of a kind of bacteria, study finds

A fruit fly genome is not a just made up of fruit fly DNA – at least for one fruit fly species. New research from the University of Maryland School of Medicine's (UMSOM) Institute for Genome Sciences (IGS) shows that one fruit fly species contains whole genomes of a kind of bacteria, making this finding the largest bacteria-to-animal transfer of genetic material ever discovered. The new research also sheds light on how this happens.

Study shows cellular differences in brain development between modern humans and Neanderthals

Dresden and Leipzig researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.
