Black people with natural blonde hair – Everything is possible in genetics

August 07, 2019 – Blonde hair is a rare human phenotype found almost exclusively in Europe and Oceania. Human pigmentation varies considerably within and among populations and is a function of both variation in exposure to ultraviolet radiation (UVR) and the type and quantity of melanin produced in melanocytes and keratinocytes.

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,

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,

Children: Is there personalized medicine for children too?

April 04, 2017 – Personalized medicine, also referred to as precision medicine, incorporates the individual patient’s characteristics into treatment, rather than relying on population means. Over the past several years, it has become a significant focus for research. Developments in pharmacogenomics, the study of genomic variations that influence response to drugs,

  • Descendants of early Europeans and Africans in US carry Native American genetic legacy September 19, 2019
    Many people in the U.S. do not belong to Native American communities but still carry bits of Native American DNA, inherited from European and African ancestors who had children with indigenous individuals during colonization and settlement. In a new study published 19th September in PLOS Genetics, Andrew Conley of the Georgia Institute of Technology and […]
  • IGF1 gene is essential to adult tendon growth, animal study shows September 19, 2019
    Tendon injuries are among the most common injuries seen in athletes at all levels, from weekend warriors to professional basketball players. For those who rupture their tendons, returning to the same level of physical activity they enjoyed before the injury is rare.
  • Researchers create new protocol to improve gene therapy tool production September 19, 2019
    A method to create a faster and lower cost alternative for a gene therapy tool has been developed by Boston University School of Medicine (BUSM) researchers.
  • Genetic variants with possible positive implications for lifestyle September 19, 2019
    A German and British research team lead by Technical University of Munich (TUM) has examined the interplay between genetics, cardiovascular disease and educational attainment in a major population study. Genetic variants which had been linked to educational attainment in other studies were observed in the subjects. The researchers found that these variants also had implications […]
  • Scientists develop new methodology to genetically modify lab mice and human cells September 19, 2019
    A team led by Cedars-Sinai has designed a rapid method to genetically alter laboratory mice and then used this method to produce personalized animal models of pediatric glioma, an aggressive type of malignant brain cancer in children.
