The diversity of Asian genomes

January 26, 2020 – An effort to map thousends of genomes across Asia has certainly the potential to find novel gene variants affecting disease and responses to drugs, and to reveal the complex origins of Asian populations.

In a pilot study,

Hidden secrets in African genomes revealed by large scale sequencing

October 20, 2019 – Sequencing African genomes yields new data resource with broad applicability. By collaborating globally in a new, large-scale effort, researchers have made strong progress in sequencing genomes from regions and countries across Africa. These findings will enable more broadly representative and relevant studies ranging from basic through clinical genetics.

Gene expression and ethnicity: Does it matter?

December 05, 2017 – We are entering the age of precision medicine, in which diagnosis and therapy decisions for each patient will be based on detailed genetic and molecular fingerprints. Unfortunately, much of the revolutionary work that underpins precision medicine has been conducted on populations of European (Caucasian) descent,

DNMT3B gene variant influences nicotine dependence

December 09, 2017 – Newest research has revealed that a DNMT3B gene variant influences nicotine dependence identified in people of European (Caucasian) descent and African-American decent as well.

Thus, a DNA variant, located in the DNMT3B gene and commonly found in people of European (Caucasian) and African-American descent,

Cancer is not like cancer: Ethnic background matters

November 24, 2017 – New research indicates that one-size treatment for one form of blood cancer likely does not fit all, particularly when it comes to ethnic differences of patients.  Thus, African-American men are three times more likely to be diagnosed with multiple myeloma,

Ashkenazi Jewish Women: Little-known Gene Mutations May Boost Breast Cancer Risk

July 27, 2017 – Jewish women of Ashkenazi descent may be at risk for additional genetic mutations that increase their risk of breast cancer, according to a new study just published in JAMA Oncology. Researchers from University of Washington in Seattle found that around 4 percent of Ashkenazi Jewish women without well-known founder mutations in BRCA1 and BRCA2 genes have other mutations that may increase their risk for breast cancer.

  • Gene that protects against osteoarthritis identified December 2, 2020
    Osteoarthritis is one of the most common problems associated with aging, and although there are therapies to treat the pain that results from the breakdown of the cartilage that cushions joints, there are no available therapies to modify the course of the disease.
  • Treating brain diseases now possible December 1, 2020
    Neurological diseases of the brain such as dementia, autism and schizophrenia are now a growing social problem. Nevertheless, studies on their definitive cause are still insufficient. Recently, a POSTECH research team has identified the mechanism in which such neurological diseases occur, thus solving the enigma to treating them.
  • Scientists identify new genetic MND risk factor in junk DNA December 1, 2020
    A new genetic risk factor for Motor Neurone Disease (MND), which if treated could halt or prevent the degenerative condition, has been identified in so-called 'junk DNA' by scientists at the University of Sheffield. The newly discovered genetic changes are present in up to one percent of MND patients.
  • Genomic analysis of mako shark reveals genes relating to tumor suppression in humans December 1, 2020
    Anecdotal reports claim that the incidence of cancer in sharks is very low, but there is not enough data to confirm this estimate categorically. A study published in the journal Genomics, however, presents strong evidence of anti-tumor activity in the genome of the Shortfin mako shark, Isurus oxyrinchus.
  • A large-scale tool to investigate the function of autism spectrum disorder genes November 30, 2020
    Scientists at Harvard University, the Broad Institute of MIT and Harvard, and MIT have developed a technology to investigate the function of many different genes in many different cell types at once, in a living organism. They applied the large-scale method to study dozens of genes that are associated with autism spectrum disorder, identifying how […]
