Discovery May Explain Higher Asthma Risk in Blacks

Julie Steenhuysen, MSNBC, August 1, 2011

U.S. researchers have discovered a genetic mutation unique to African Americans that could help explain whyblacks are so susceptible to asthma.

Prior studies looking for asthma genes have turned up several, but most of the studies have been too small to confirm these genes or to detect genetic changes unique to different races.

The new study, published on Sunday in the journal Nature Genetics, pools research from nine different research groups looking for genes associated with asthma among ethnically diverse North American populations.

It confirmed four genes that had been seen in previous studies and a fifth that shows up only in people of African descent.

    Genetic marker hogwash. Blacks live in polluted urban areas.

    I have been told that more and more research is showing that the last three weeks of human gestation is critical to the mother passing her immune system to her about-to-be-born child, the obvious conclusion being that those born three or more weeks prematurely are way more susceptible to asthma and allergies. Could part of the reason so many black children have asthma and allergies is because so many of them are premies?

    I had heard that the farther away from africa that an african gets, the asthma worsens…….. the best they can hope for is, that in africa it is milder, so if they stay there, or go back, the asthma weakens.

    Researchers have discovered “a genetic mutation unique to African Americans”. Does this mean that the genetic marker doesn’t occur in black Africans in Africa? LOL.

    Even when talking about something as central to race as a unique DNA mutation, the PC controlled media cannot mention the actual race involved but has to resort to this convoluted PC term, African American.

    Is it not so that race is a “social construct” with no physical distinctions as pushed by Franz Boas? These brainwashing institutions called schools better get their stories/lies straight. The other most prominent stories/lies are that blacks came out of Africa spreading their superior genes everywhere, they are the mother race, and all ancient technical advances came from blacks. The whites stole all their advance ideas. It is even posted on the Internet that the blacks actually wrote the Constitution and the Founding Fathers had stolen it.

    That’s so outrageous it has to be true, and typical.

    Why are whites more susceptible to Cystic Fibrosis?

    I suspect that the the geneticists are learning a lot more about the realities of race than the pc medically relevant information that trickles out.

    #2 raises the point of premature babies. I don’t know if this is the case in Africa but I wouldn’t be surprised. If it is then why hadn’t it been quickly been selected out. The Black subspecies evolved a strategy of fast maturation outweighing high infant mortality.

    Because, social scientist like yourself, are clearly experts in the field.
