Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 17, one copy inherited from each parent, form one of the pairs. Chromosome 17 spans about 79 million base pairs (the building blocks of DNA) and represents between 2.5 percent and 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 17 likely contains between 1,200 and 1,500 genes.
Genes on chromosome 17 are among the estimated 20,000 to 25,000 total genes in the human genome.
Risky behavior can lead to premature death - in humans. Anna Lindholm and her doctoral student Yannick Auclair investigated whether this also applies to animals by studying the behavior of 82 house mice.
Pharmacyclics, Inc. today announced that The New England Journal of Medicine published results of a Phase 2 study evaluating the investigational oral Bruton's tyrosine kinase inhibitor ibrutinib in patients with relapsed/refractory mantle cell lymphoma online.
Pharmacyclics, Inc. announced today that the U.S. Food and Drug Administration has granted an additional Breakthrough Therapy Designation for the investigational oral agent ibrutinib as monotherapy for the treatment of chronic lymphocytic leukemia or small lymphocytic lymphoma patients with deletion of the short arm of chromosome 17 (deletion 17p).
About 90 percent of children with two copies of a common genetic variation and who wheezed when they caught a cold early in life went on to develop asthma by age 6, according to a study to be published March 28 by the New England Journal of Medicine.
The patients have single short fingers (metacarpals) and toes (metatarsals) and can be restricted in growth due to a shortened skeleton. This hereditary disease is called brachydactyly type E (Greek for short fingers).
A mutation located near the fatty acid synthase gene is associated with an increased predisposition for uterine leiomyomata or fibroids, suggest US study findings.
Using data from its unique online research platform, 23andMe, a leading personal genetics company, has contributed to the finding of six novel genetic associations for early onset male pattern baldness (androgenetic alopecia) in a genome-wide association study now published online in the journal PLoS Genetics.
Genetics researchers have identified at least two new gene variants that increase the risk of common childhood obesity.
Applied Spectral Imaging (ASI) announces that ASI's GenASIs automated scanning and image analysis system for detection and quantifying chromosome 17 and the HER-2/neu gene has been cleared by the United States Food and Drug Administration (FDA) for marketing in the US.
The U.S. Food and Drug Administration today approved a new genetic test that will help health care professionals determine if women with breast cancer are HER2-positive and, therefore, candidates for Herceptin, a commonly used breast cancer treatment.
Two new studies highlight the power of sequencing cancer patients' genomes as a diagnostic tool, helping doctors decide the best course of treatment and researchers identify new cancer susceptibility mutations that can be passed from parent to child.
Scientists have carried out the first ever genome scan for womb cancer and discovered a genetic region that reduces risk of the disease, according to a study published in Nature Genetics.
The interplay between a major tumor-suppressing gene, a truncated chromosome and two sets of microRNAs provides a molecular basis for explaining the less aggressive form of chronic lymphocytic leukemia, an international team of researchers reports today in the Jan. 4 edition of the Journal of the American Medical Association.
Researchers have identified the deletion of a genomic region on chromosome 17 as a significant risk factor for autism spectrum disorders (ASD) and schizophrenia. A mutation of one of the genes in the deleted interval already is a known cause of renal cysts and diabetes syndrome (RCAD).
In a new study seven genes linked to asthma have been discovered. For the research genetic variations of 10,365 people with asthma and 16,110 people without the condition was studied. The variants identified showed an association with childhood asthma and some were also associated with later-onset asthma.
An international consortium of scientists has discovered new genetic variants in five regions of the genome that affect the risk of ovarian cancer in the general population, according to two separate studies published today (Sunday), online in Nature Genetics.
Although clubfoot is one of the most common congenital birth defects, few genetic causes have been found. Now, researchers at Washington University School of Medicine in St. Louis have found what they believe to be the most common cause of inherited clubfoot yet discovered.
British researchers have discovered a new way of detecting which breast cancer patients are going to respond best to chemotherapy that includes anthracycline antibiotics. The study has found that an abnormality on chromosome 17, called CEP17, is not only associated with a worse outcome for patients, but also that its presence is a highly significant indicator that the tumour will respond to anthracyclines. The research will be presented at the European Breast Cancer Conference (EBCC7) Thursday 25th March.
Researchers from four laboratories that perform diagnostic genetic testing of chromosome abnormalities in individuals with unexplained physical and developmental disabilities recently identified a previously unrecognized genetic disorder.
Pediatric researchers have identified a novel gene involved in childhood asthma, in one of the largest gene studies to date of the common respiratory disease. Because the gene, called DENND1B, affects cells and signaling molecules thought to be instrumental in the immune system overreaction that occurs in asthma, the discovery may have singled out an important target for new treatments.
