African-American Study Identifies Four Genetic Variants Associated with Blood Pressure

Medical Xpress, September 10, 2013

Case Western Reserve University is part of a landmark study that has discovered four novel gene variations which are associated with blood pressure. The 19-site meta-analysis, involving nearly 30,000 African-Americans, also found that the set of genetic mutations are also associated with blood pressure across other populations.

Epidemiology and biostatistics professor Xiaofeng Zhu, PhD, is co-senior author of the paper, which appears in The American Journal of Human Genetics. The Continental Origins and Genetic Epidemiology Network (COGENT) consortium conducted the research, which is the largest genome-wide association study of blood pressure in individuals of African ancestry. {snip}

“In addition to their disproportionate suffering, hypertension occurs earlier in life for African-Americans compared to individuals of other ancestries,” Zhu explained. “Therefore, it is important to study this population to better understand  to hypertension.”

Zhu and his colleagues also confirmed that previous findings regarding other genes whose presence correlates with increased hypertension risk.


Experts estimate genetic make-up accounts for roughly 40-50 percent of individuals’ susceptibility to hypertension. Other factors associated with the disease include lifestyle, diet, and obesity. Compared to Americans of European-ancestry, African-Americans’ increased hypertension prevalence contributes to a greater risk of stroke, , and end-stage renal disease.

“We anticipated that individuals of African ancestry share similar biology to other populations. However, differences in genomic make-up between African ancestry and other populations have uncovered additional genes affecting blood pressure, in addition to genetic variants that are specific to individuals of African ancestry,” said Nora Franceschini, MD, MPH, nephrologist and research assistant professor of epidemiology at the University of North Carolina at Chapel Hill and first author on the paper.

    Wait a minute… The good mister Shlomo assured me high blood-pressure among groids was because of evil nazis . Did doctor Shlomo lie ?

    • me

      Doctor Shlomo invented the ‘raaaaycis’ Frankengroid to kill all the crackers.

    Are these genes specific to actual African ancestors? A significant percentage of the population socially defined as Afro-American has “white” or even “Amerindian” ancestry. The possibilty that this mixed-race population might have some systemic weaknesses because of crossing is something that needs to be considered objectively: the medical interest exceeds the political reluctance.

  • Diversity Awareness Brigade

    Genes be Rayciss!

    • Manaphy

      The truth is racist. Whether blacks and idiotic whites who deny the existence of race (except when promoting diversity) accept it is their choice.

      “Genes be Rayciss!”

      Word! As a black man in America I agree that this “Gene” guy be rayciss fo’ givin’ us hypertension.

      Dis Gene must be da same white boy who sings fo’ KISS. He always be stickin’ his tongue out at da sistahs…

    Blacks targeting Whites for brutal attacks and murder.

    And I should give a **** about their blood pressure WHY??


  • bigone4u

    Blacks got shortchanged by evolution: stupid, bad health, no self-control over their murderous impulses. And once again white tax dollars are spent to solve their health problems. What garbage. The government of the former USA will one day be held accountable for squandering our wealth. Or so I hope.

      And the Chinese laughing while they become the next Global Power.

        There’s an interesting article over at AltRight that discusses the newfound fascination in South Korea and Japan for negroes. The insanity is spreading.

        • Bossman

          The “negroes” would give East Asian women some curves. They’ve none.

  • Whitetrashgang

    They have high blood pressure because they have to live around other blacks. Problem solved, high five.

  • Nick A Siggers

    But low IQ in the black race is still totally environmental, and mostly because of racism.

  • Rick Brooks

    Geee, I thought race was an arbitrary social construct. After all, that’s what my local PBS station told me a number of years back. I’m so confused.

  • Ni123


    But try to say that there are genetic variances associated with intelligence specific for blacks and Hispanics and you will be ostracized.

  • HJ11

    Genes are us.

    There isn’t a one size fits all human.

    Blacks aren’t the same as Whites. Trust your eyes, they’re usually right.

  • Erasmus

    If genetics wasn’t a racist science, then why was modern gene theory first formulated by a white, Christian monk, Gregor Mendel?
    Hmmmm, answer me that!
    (sarcasm off)

  • Bossman

    This article is very vague. Blacks should exercise a lot in the sunshine. Stay away from salty foods and don’t drink and eat too much except for water. Their high blood pressure has a lot to do with their kidney functions and lot less with the clogging of the arteries.

  • HJ11

    Yup. The Blenders want to conditon Whites into thinking there are no differences between Whites and Blacks. Remember Jimmy the Greek, who was run off the air because he indicated that Black football players have a different thigh structure than Whites?

    He was actually saying something positive about Blacks, but because he indicated there was a racial difference he had to go.

  • HJ11

    Slightly off topic: Although Blacks are responsible for the killing of many Whites, the Black propensity for violence actually puts them at a survival disadvantage to Whites in the modern world. Many are caught and thrown in prison. Many die. This means they don’t breed.

    • Jenkem Huffington

      Don’t look now, but they breed like rodents. It’s hard to find a sow without a few sprogs by the time they’re 20, and given the promiscuity and over-sexed nature of the bucks, even if a plague killed 90% of the males, the remaining 10% would easily keep in with impregnating all the sows to maintain their natural breeding levels.

    • prunepit

      The “modern world” includes Africa where their breeding habits compensate fully for their “propensity for violence” and occasional incarceration. In our country 600,000 Africans have grown to 40 million in just a hundred fifty years. Interference with a group’s natural habitat and its survival and breeding abilities has its consequences.

    • David Ashton

      Some don’t breed. Others make up for it.

      • JohnEngelman

        And whites pay for their child support with welfare checks.

    • JohnEngelman

      Civilization has evolutionary pressures in favor of superior intelligence, and against physical aggressiveness.

      In the neolithic environment the Bantu lived in there was less evolutionary pressure for intelligence. Physically aggressive men attracted more wives, or “casual brides,” and had more children.

      American Negroes are several generations removed from an environment where the most successful killers had the largest number of sons, who inherited their violent inclinations and talents.

      Qualities that had survival value in the African jungle frequently earned one a date with the executioner in civilized countries.

      • David Ashton

        How do you get from a neolithic environment with negative selection for intelligence over physical strength to a civilization with the reverse criteria?

        See if you, and other readers, can get on the internet David Attenborough’s recent comments on human evolution coming to an end and on population pressures, which annoyed Matt Ridley and other more PC “biologists”.

        • JohnEngelman

          A paleolithic and a neolithic environment does select for intelligence. Otherwise, humans would not have evolved to become more intelligent than our nearest relatives, the chimpanzees.

          However, urban civilization places more evolutionary pressure on superior intelligence. Intelligent men become merchants, money lenders, government officials, and so on. These are more prosperous than laborers, and during nearly all of history they have been more prolific.

          • David Ashton

            Money-lenders? Anyone special in mind?

  • Jenkem Huffington

    The double-think required to follow this narrative is really amazing. They’re “just like us” but with a different paintjob but we should feel sorry for them and fund studies to find our why they are unhealthy…. Genetics and bad behavior. Or perhaps genetics and bad behavior due to genetics?

    No mention of IQ differences. I guess that is still forbidden.

    • David Ashton

      Why “anticipate” something long ago realised as hypothetically improbable and demonstrated as incorrect by numerous studies, including relatively recentDNA sampling, quite apart from brain variation and brain-performance issues?

      • David Ashton

        PS. – Stanley Garn’s “Human Races” noted many differences not only in anatomy but biochemical functioning so long ago as 1961, but of course Darwin, Tylor, Huxley and Galton were on to it long before, naturally denounced as “racists” by sociology textbooks de nos jours.

  • RyanP

    I remember hearing a few years ago that black hypertension was caused by the stress of white racism. But how about that, a genetic explanation. Maybe there are some other traits with a genetic component as well. 🙂

  • David Ashton

    Poor old Al Jolson – he forget to take his ACE inhibitor thus morning. Or perhaps he noticed the encomia of lynching among the AmRen posts.
