According to the article Sickle Cell and Black Genocide, Wilbur Johnson and Mae Sanford, both African American, had met while working on a community action project in a larger Eastern city. After going together for a year, they decided to get married and have a family.
Lester Kettering, Mr. Johnson’s physician, asked if Mr. Johnson knew his sickle cell status and explained if he and his wife were carriers, they had one chance in four that any child born to them would have the disease. Also, he explained that they would also have two chances in four that a child would be a carrier, while in one of four births the offspring would carry no copies of the gene. Dr. Kettering also explained that it was state law that any children born would be routinely

Sickle cell disease is autosomal recessive; that is, both parents must have at least one copy of the gene before there is a risk of producing children with the disease (homozygotes). When both parents are carriers, the risk of bearing such a child is 25 percent with each pregnancy. Carriers themselves are almost symptomless and may have no idea of their status unless they are screened.
Moreover, Mr. Johnson’s younger brother died in adolescence from the disease, after many painful and debilitating attacks. He thus knew it was a possibility that he himself was a carrier. Mr. Johnson also knew that the trait is fairly common among African Americans, about one in twelve is a carrier, so there was a good chance his fiancée was a carrier too. Ms. Sanford knows of no sickle cell disease in her immediate family, but she is in a racial group with a relatively high rate of

If the parents choose to opt out of getting a sickle cell test done for their infant than it should be their decision. This would fall under the principle of autonomy. Autonomy demonstrates respect for persons as it allows for independence over one’s decisions and choices. However, if the child were born with this disease it would cause harm to the child as well as the parents. I would want a test for my child; if I knew there was a chance my husband and I were carriers. The severity of this inherited abnormality could almost severely handicap this child. This is weakly justified to Mr. Johnson as well as to myself. I believe that there should be some sort of health insurance to help this disease. As a parent it is their duty to do everything in their power to have a normal and healthy baby.
I do not believe that mandating newborn testing is crippling the black reproductive capability because why wouldn’t you want to know what’s wrong with your child. If doctors see that this disease is genetically inherited it is their duty to look out for their patient’s best interest. Mr. Johnson’s refusal should be respected because he has the freedom and beliefs to do so. It shows that Mr. Johnson has some resentment towards the white society. He does not fully trust his physician best interest. There is no cure for this disease
Dorothy Roberts is social justice advocate and law scholar who preaches the message that race-based medicine is bad medicine. She believes that doctors use race, instead of tests and observations, as a shortcut to give diagnoses. Her main argument is that there is only one race, the human race. In her Ted Talk, Roberts goes over statistics to explain why she thinks that race-based medicine is barbaric and shouldn’t be practiced.
Furthermore, these doctors had no legal or ethical codes to conduct experimentations or research on African Americans. For example, during 1998, “172 employees, all but one of them black, sued Lawrence Berkeley Laboratory when they learned that they had secretly been tested for syphilis, pregnancy, and sickle-cell trait without their knowledge that the blood and urine they had supplied during required physical examinations would be tested…” (314). This indicates that there was no consent from these blacks and scientists where secretively testing immunities for sickle-cell on them without any permission whatsoever. The release of this experiment was against the Americans with Disabilities Act and these researchers had no right to release information without the patient’s consent. Furthermore, experiments that had no patient’s consent varied from blisters “to see how deep black skin went” to threatening surgeries, sterilization, inoculations, and not tested pharmaceuticals (54). Without consent, all experiments are considered as unethical. A patient’s consent is important because it is huge determination of privacy and respecting the patient’s wishes. Without any consent, it is indicating that patient’s do not have rights about their own privacy, which was against the law during colonial times and in present days. Some ethical guidelines include the right to withdraw from the study
The distrust between the African American community and white medicine has been a factor far before Henrietta, but her story definitely contributed to the long history. Had Henrietta been white, I am almost sure that she would be a national hero and historical figure. Through this course was my first time even coming across this story, but I want more to know about it. If the cure for cancer is ever found it would only be fair to give Henrietta over half the credit. Nevertheless, we are still making strides towards racial equality as it goes hand in hand with informed consent. We have to educate more African Americans on what informed consent is so that there are no more cases like Henrietta. You have the right to know what is being done or not being done to your body, and you should have the option to not only decide your fate, but understand the pros and cons of each
Black Holocaust for Beginners “Death Ships”, is a realistic, and trapping article about the slave trade. Instead of the former stories on slavery and giving it a general description telling reader how slavery is bad and slavery is immoral, this article goes in and describes what it was like in a slave ship. It made the reader feel the pain of the middle passage in every page.
In the book it says "They can spend a whole lifetime worrying whether they 're carriers, and then we come along and offer them a test. Recessives and X-linked. Look what they 're doing with fragile-X nowadays. And cystic fibrosis. Just imagine the commercial possibilities if you can design and patent a probe for something like Gaucher 's disease...(69)" Recessive traits is the phenotype is seen only a homozygous recessive genotype for the traits of the interest is present. The booked talked about two of three diseases that are most common in the Ashkenazi Jewish population. The first one is Cystic fibrosis which is an inherited life-threatening disorder that effects the lungs and the digestive system. The other one mention in the book that wasn’t mention in class was Gaucher 's disease. Gaucher 's disease is a build up of fatty substances in your organs, usually in you spleen and liver. Which causes them to become bigger affecting their function. The last one that we learned in class was Tay-Sachs disease, which is a rare inherited disorder that destroys nerve cells in the brain and spinal
Even to present day the there is still a bias among doctors when it comes to treating and diagnosing of black people.The things that kill black the most are preventable and curable Washington says“that blacks are not dying of exotic, incurable, poorly understood illness nor from a genetic disease that target them only but rather from common ailments that are more often prevented and treated among whites than among blacks”(Washington 2006). The most experiment that show how true this statement is the Tuskegee syphilis experiment sponsored by the government of the United States. In this famous experiment, black was infected with the bacteria that causes syphilis.This ...
Hemoglobin SS happens because of a mutation in chromosome 11. Chromosome 11 contains the gene of hemoglobin-Beta. Hemoglobin (HBB) transports oxygen to your body parts like your lungs. Hemoglobin contains 2 alpha hemoglobin and 2 beta hemoglobin chains. Sickle cell anemia results from a point mutation. There is a change in the sixth amino acid in the beta hemoglobin chain from GLU to VAL. The Hemoglobin S gene is then resulted from this and is a rece...
Medical research in the United States has a disgraceful history of exploitative studies in which African Americans were targets of abuse in the name of medical and scientific progress. African Americans have been used as the testing ground for drugs, treatments, and procedures since the time of slavery. The tolerance of the human frame and the endurance of the soul have been pushed to the limit in many of these experiments. From the physical demands on plantation work and the torturous treatment of slavery to the mental anguish inflicted on a slave’s soul by their masters, blacks have received deplorable treatment sanctioned by a white society. The end of slavery and the ushering in of the twenty first century did not end the torturous treatment and mental abuse. African Americans have been used for medical experimentation without consent for decades. Ironically they are treated as inferior and often given fewer rights than others, but amazingly their cells and bodies are treated as equals in laboratories for medical research, the results of which can save, extend and enhance the lives of others. Although color lines that are drawn in many aspects of life and inequitable treatment doled out based on the depth of the color of one’s skin, actually astounding results from medical experimentation on African Americans has produced drugs, cures and treatments for even those who do not value people of color, leaving the question of ethics and equity hanging in the balance.
Sickle cell was first discovered by Dr. Ernest irons that was a hospital intern who look over a patients cell which seem to be different he called them “sickle cell shaped”. Sickle cell is know as a negro inherited diseases which is incorrect not only African Americans have this diseases. Many other races are effect by this diseases and regions all over the world such as India, Mediterranean countries, South American. In this case sickle disease work kind of like vaccination for malaria another diseases, this is the most common inherited disease in American. Anyone who has sickle trait and have a baby with someone who has the trait also can bring a baby into the world the world with SCD.
...that Satel needs to do more research. For example, in her article, she mentions that Primary-care physicians who lack board certification and who encounter obstacles to specialized services are more likely to practice in areas where blacks receive their care—namely, poorer neighborhoods, as measured by the median income, but she doesn’t back it up with research. Although some may object that health care is color blind and that doctors do their best to administer health care proportionately, I would reply that racism plays a role in the health care disparities. Racism has always been an issue and there is no way people can reject that fact. This issue is important because the health care disparity gap is large and something needs to be done about it. As IOM said, people need to be aware of what is going on so as to take appropriate steps in order to break the gap.
If only one parent is a carries that child may only inherit that trait sickle cell cannot be contracted or pass from one individual to the next sickle cell is consider and autosomal recessive discover. It gets pass down from generation to generation.
In June of 1999 all hospitals in the state of New York were notified by the New York State Department of Health that beginning August first, 1999, a radical new approach to HIV screening was to be initiated. According to the policy, "for those women without prenatal HIV test results who decline HIV testing during delivery, hospitals are required to conduct expedited HIV testing of all newborns" (New York State Department of Health, June, 1999). This policy was the consequence of a heated debate in the legislature over the results of anonymous HIV screening performed on pregnant women in the state of New York (Cameron, 2002). New York State had been engaged in anonymous testing of newborns since the late 1980s, and this testing consistently reve...
The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be addressed: When should genetic testing be used? And who should have access to the results of genetic tests? As I intend to show, genetic tests should only be used for treatable diseases, and individuals should have the freedom to decide who has access to their test results.
Sickle Cell Anemia is an inherited blood disorder that is extremely challenging to live with. Its symptoms are many, with the most prominent being severe pain that can become unbearable to the point where hospitalization is required. Because sickle cell is a genetic disorder, a person is born with it and it is usually permanent. Unfortunately, there are risks and complications associated with this disease. However there are various treatment options for a patient with sickle cell and also support to help people understand and cope with this challenging disease.
First of all, I want to start by saying that I 'm not discriminating the disabled community, but this is a very large number that could possibly be diminished with the help of genetic testing. (1) I believe that there is nothing wrong with testing the genes of an unborn child to possibly determine if it could develop a genetic disorder in the future. One of the advantages that genetic testing provides is that the parents could now be informed of the situation, and keep track of their unborn child 's health. I 'm sure those parents are pleased with this technology, and the chances to be able to keep track of their baby. This a baby, and is something very precious, and valuable, and I believe that parents want to keep track of anything that may happen with the unborn child. I 'm sure that a large amount of people would agree would agree that they don 't want to suddenly take the hard hit. When the news is presented in the delivery room. This serves more as an advantage than a disadvantage, due to the fact parents. Pull be more prepared, or possibly have the option to abort it. This is a right that the parents should have regardless of the opposing side arguments towards it. Im a hundred percent sure that the opposing side has very strong arguments towards genetics testing, and one of the main ones is "playing God." The opposing side believed that some things in
