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.

ZRANB3 in African Populations: New Type 2 Diabetes risk locus identified

August 03, 2019 – Africa is considered the original cradle of all humanity, to which all humans can trace their genetic origin. This may be very interesting in the context of diseases that are due to genetic predispositions both in todays African populations and in all the populations descendant of African origin worldwide.

Genetic aspects of globesity: Glocalized or not?

June 25, 2019 – The global obesity epidemic is so far-reaching it now has an overarching name: globesity (obviously derived from global obesity).  Very interesting questions arise in this context such as are there glocalized (global and or local) factors involved in this epidemic.

Creative dancing and the genetic predisposition of it

May 06, 2019 – Dancing, integrally related to music, likely has its origins close to the birth of Homo sapiens. Some researchers for a long time have hypothesized that there are differences in aptitude, propensity, and need for dancing that may be based on differences in common genetic polymorphisms.

Genomics lab illegally markets genetic tests that claim to predict patient responses to drugs

April 07, 2019 – Consumers are increasingly embracing genetic testing to better understand their individual risk for developing diseases. With this rise in popularity and availability, we’re also seeing significant activity in the field of pharmacogenetics, which is the process of understanding what, if any, role genetics plays in a patient’s reaction to particular drugs,

  • Researchers find genetic links to child obesity across diverse ethnic groups August 22, 2019
    An international team of researchers who analyzed data across multiple ethnicities has produced the largest genetic study to date associated with common childhood obesity. The Early Growth Genetics (EGG) Consortium discovered a robust new signal, fine-mapped previously reported genetic variants, and added to evidence that genetic influences on obesity operate across the lifespan.
  • Researchers develop model to personalize radiation treatment August 22, 2019
    A personalized approach to cancer treatment has become more common over the last several decades, with numerous targeted drugs approved to treat particular tumor types with specific mutations or patterns. However, this same personalized strategy has not translated to radiation therapy, and a one-size-fits-all approach for most patients is still common practice. Moffitt Cancer Center […]
  • How our genes and environment influence BMI and height August 22, 2019
    Environmental conditions influence our body mass index (BMI) by increasing or decreasing the effect of inherited genetic variations, University of Queensland researchers have discovered.
  • Genetic testing and family tree research are revealing painful family secrets, research says August 22, 2019
    Genealogical research and genetic testing are revealing skeletons in family closets and causing rifts among members, a new study shows.
  • Researchers use single-cell sequencing to get a better look at human embryo implantation August 22, 2019
    A team of researchers affiliated with multiple institutions in China has used single-cell sequencing to learn more about the human embryo during implantation in the uterus. In their paper published in the journal Nature, the group describes sequencing thousands of human embryo cells from before, during and after implantation, and what they learned from it.
