Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 9, one copy inherited from each parent, form one of the pairs. Chromosome 9 is made up of about 140 million DNA building blocks (base pairs) and represents approximately 4.5 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 9 likely contains between 800 and 1,300 genes.
Genes on chromosome 9 are among the estimated 20,000 to 25,000 total genes in the human genome.
Researchers from The University of Texas MD Anderson Cancer Center are presenting compelling findings from three clinical trials at the 2022 American Society of Hematology Annual Meeting.
Amyloid plaques — protein clumps that are one of the hallmarks of Alzheimer's disease—occur at roughly the same level in the brains of people with Down syndrome who have Alzheimer's as they do in people with forms of hereditary, early-onset Alzheimer's, according to research funded by the National Institutes of Health.
When the normal DNA sequence in an individual changes or mutates it can cause disease. The mutation may involve multiple genes and may be caused by environmental factors, or there may be chromosomal defects that are harmful at birth, in infancy or environment at a later stage.
In this interview, NewsMedical speaks with Rainu Wau from International Maternal and Children’s Hospital, Shanghai, China, about her experience using whole exome sequencing and carrier screening tests.
In this interview, Ryan Muise talks to AZoNetwork about the added value of using flow cytometry in CAR T-Cell clinical trials.

These funds, coming from the Menkes International Association, will allow a research project to search for new biomarkers to establish administration and monitoring protocols for a new drug that could improve the lives of children suffering from this rare disease.
In a new study, researchers reviewed the genomics, transcriptomics, and epigenetics of asthma exacerbations (AEs).
Building on the CRISPR gene-editing system, MIT researchers have designed a new tool that can snip out faulty genes and replace them with new ones, in a safer and more efficient way.
Scientists at UF Scripps Biomedical Research have developed a potential medicine for a leading cause of ALS and dementia that works by eliminating disease-causing segments of RNA. The
Two recent papers by Brazilian researchers have contributed to the scientific understanding of the genetic factors that protect people against infection by SARS-CoV-2 or prevent progression to severe COVID-19.
The liver’s ability to regenerate itself is legendary. Even if more than 70 percent of the organ is removed, the remaining tissue can regrow an entire new liver.
Patients with head and neck cancer who have more genetic material on chromosome 9 in their cancer cells survive three times longer after receiving immunotherapy than those with less genetic material there, a new study finds.
An immune response that likely evolved to help fight infections appears to be the mechanism that drives human immunodeficiency virus (HIV) into a latent state, lurking in cells only to erupt anew, researchers at Duke Health report.
Scientists at the University of Pittsburgh School of Medicine have discovered the missing puzzle piece in the mystery of how melanoma tumors control their mortality.
Model organisms are essential for biomedical research and have enabled many important scientific discoveries. The ability to sequence the genomes of these models is a powerful tool to study the genetic factors that impact human health.
In a recent study published in the journal Cell, researchers examined the phenotypic landscape of multiple elusive essential human genes to create a detailed genotype-phenotype resource outlining the phenotypic consequences of disrupting fundamental cellular processes.
A genetic test known as chromosomal microarray analysis (CMA) could help identify the cause of sudden infant death syndrome (SIDS) or its counterpart in older children, known as sudden unexplained death in childhood (SUDC), finds a study led by Boston Children's Hospital.
