Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 16, one copy inherited from each parent, form one of the pairs. Chromosome 16 spans about 89 million base pairs (the building blocks of DNA) and represents almost 3 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 16 likely contains between 850 and 1,200 genes.
Genes on chromosome 16 are among the estimated 20,000 to 25,000 total genes in the human genome.
A team of WA researchers has uncovered new genes that could play an important role in the development of sarcoma, a group of rare bone, muscle and connective tissue cancers.
Whether an individual develops a neurodevelopmental disorder like autism or ADHD and the severity of that disorder depends on genetic changes beyond a single supposedly disease-causing mutation.
Genes located in a large chromosomal aberration associated with autism interact with each other to modulate the variable symptoms of the disease, according to new research.
In a new study of one of the most common genetic causes of autism, neuroscientists at MIT's Picower Institute for Learning and Memory have identified a specific molecular mechanism that appears to undermine the ability of neurons in affected mice to properly incorporate changes driven by experience.
Scientists have identified a pair of treatments that may restore brain function to autism patients who lack a gene critical to maintaining connections between neurons, according to a study from the Peter O'Donnell Jr. Brain Institute at UT Southwestern Medical Center.
For the first time, Whitehead Institute scientists have documented a direct link between deletions in two genes--fam57ba and doc2a--in zebrafish and certain brain and body traits, such as seizures, hyperactivity, enlarged head size, and obesity.
In rare cases -- for instance, among siblings in two families from Pakistan and Oman described in a new study -- children have been born with an unnamed neurological disorder.
A new study in Biological Psychiatry reports that variations in 16p11.2, a region of the genome associated with risk of autism spectrum disorder (ASD), have distinct effects on cognition. The findings highlight the diversity of people with ASD.
Research led by investigators in veterinary and human medicine has identified genetic pathways that exacerbate severity of canine compulsive disorder in Doberman pinschers, a discovery that could lead to better therapies for obsessive compulsive disorder in people.
Resistance to CD19 CAR T-cell therapy, a type of immunotherapy that yields long-lasting remissions in many patients with B-cell leukemia, can be caused by CD19 splicing alterations, leading to loss of certain parts of the CD19 protein that are recognized by the CAR T cells.
A new study of more than 25,000 men has uncovered four new genetic variants associated with increased risk of testicular cancer.
Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerning the mechanisms leading to birth defects and chromosome instability in cancer cells.
A novel molecule designed by scientists at the University of Massachusetts Medical School and the University of Virginia inhibits progression of a hard-to-treat form of recurring acute myeloid leukemia (AML) in patient tissue.
Genomics researchers analyzing a rare, serious immunodeficiency disease in children have discovered links to a gene crucial to the body's defense against infections. The finding may represent an inviting target for drugs to treat common variable immunodeficiency (CVID).
Children born with a DNA abnormality on chromosome 16 already linked to neurodevelopmental problems show measurable delays in processing sound and language, says a study team of radiologists and psychologists.
In a new study published in Cell Reports, scientists at the Fred Hutchinson Cancer Research Center demonstrate that mice lacking one copy of a gene called CTCF have abnormal DNA methylation and are markedly predisposed to cancer.
Several studies have looked at possible links between maternal obesity during pregnancy and the risk of developmental disorders in the child. However, paternal obesity could be a greater risk factor than maternal obesity, according to a new study from the Norwegian Institute of Public Health.
An international consortium co-led by researchers at Fred Hutchinson Cancer Research Center and the QIMR Berghofer Medical Research Institute in Australia has identified four genetic variants associated with an increased risk of esophageal cancer and its precursor, a condition called Barrett's esophagus.
Combining hospital MRIs with the mathematical tool known as network analysis, a group of researchers at UC San Francisco and UC Berkeley have mapped the three-dimensional global connections within the brains of seven adults who have genetic malformations that leave them without the corpus callosum, which connects the left and right sides of the brain.
Mice with a condition that serves as a laboratory model for Down syndrome perform better on memory and learning tasks as adults if they were treated before birth with neuroprotective peptides, according to researchers at the National Institutes of Health.
