Review Questions # 5 2. Distinguish between autosomal dominant and autosomal recessive disorders and provide a couple examples of each. When dealing with genetic disorders its important to understand how they are inherited. There are two ways a child can inherited a genetic disorder from their parents. Autosomal dominant disorder is where one parent has a genetic disorder in which it has already manifested such as familial hypercholesterolaemia, marfan’s syndrome, and achondroplasia(dwarfism) and this dominant gene is inherited by their child who will also develop the disorder.…
There is still a chance that it will not be passed down, but more than likely it will be. With that though, if the alleles that are being passed down are both dominant; than the alleles are both shown and that is called codominance (Barekzi, 2016). There are two other possibilities for dominant traits as well. Those are complete dominance and incomplete dominance. Complete dominance is when the offspring only looks like one of their parents and not like the other and incomplete dominance occurs when the offspring does not look like either one of its parents (Barekzi, 2016).…
If an individual inherits one normal gene and one mutated gene, the person will be a carrier for MSUD. The risk for two carrier parents to both pass the mutated gene and have an affected child is 25% with each pregnancy. The risk to have a child who is a carrier like the parents is 50% with each pregnancy. The chance for a child to receive normal genes from both parents is 25%. The risk is the same for males and females according to the National Organization for Rare Disorders (NORD.…
The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the…
Dementia is an umbrella term. By this I mean that it covers many different conditions. Each condition affects the brain and can lead to dementia due to brain de deterioration and loss of function. Wernicke-Korsakoff syndrome- this is a brain disorder in which not getting enough B1 vitamin will affect your brain function. B1 vitamin is used in the brain to change sugar into energy.…
Frequency of cystic fibrosis is within 2 months when you are a baby as the doctors will check you. Cystic fibrosis is more common with Caucasians in the United States. The disease occurs in 1 in 2,500 to 3,500 Caucasian newborns.…
A kid can get the gene passed down to them but not necessarily have the disease. If both the parents carry the gene, then one in four children will actually have the disease. If the parents have four kids, one will have the disease, one will carry it and the other two children will have no remains…
FM 4 Familial Hypercholesterolemia also known as FM, is a disease of extremely high cholesterol levels beginning early in gestation. It is passed along from family member to family member through a genetic mutation. Most commonly on chromosome 19. Many other chromosomes have now been identified as causing familial hypercholesterolemia such as (apo) B-100 (FDB, OMIM 144010).…
Meghan was two when her father was diagnosed with Huntington's. At the time, she didn't understand what that was. In 2006, in College, while pouring herself some lemonade, she spilled the pitcher and knocked her glass on the floor. When her mother was helping her clean up the mess, Meghan told her she thought she had Huntington's disease. Her mother has seen the symptoms for a few years, and she finally told her that she knew.…
Depending on the reliability of the person contraceptives that require people to be responsible the percentages go down. Perfect use of a contraceptive lowers the possibility of pregnancy. If a person does not take the pill every day regularly or does not put the condom on correct the percentage of pregnancy increases. It is said that “condoms are 98 percent effective” when used properly. If a male does not perfectly use the condom the “failure rates increase to 18 percent” () People that inconsistently use contraceptives have almost as high of a percentage as nonusers.…
HD is a dominant gene, which mean others in the family will show the same symptoms but didn’t. There was one family recorded with HD, which was the Bures family. The members of the family were accused frequently for witchcraft and convicted of this crime” (faas.org et al). Bures was probably the only notable family with HD and were convicted because of their symptoms displayed. This shows that only a few people had HD and it does not explain the illness showed by others in Salem.…
In saying this, it grants them rights previously denied to born individuals (Minkoff and Paltrow, p.758). There is no way to guarantee a pregnant woman has the same…
Introduction The scientific study of Huntington’s Disease (HD) had began in 1872, by George Huntington who is a family physician that had published a report on the clinical symptoms and peculiar mode of inheritance of the disorder.(1, 2) Huntington’s disease has 3 subtypes according to the age onset, which are infantile, juvenile and the adult-onset.(2) Individuals with Huntington’s disease can become asymptomatic between the ages of 1 and 80 years.(3) The typical mean age of onset is 40 years, with death occurring 15–20 years from onset.(2, 4) The prevalence of HD patients in North America and Europe is 0.005% - 0.01%. It is lowest in Africa and Asian population compared in western European origin population.(5) The clinical symptoms for HD are divided into 3 categories: psychiatric disorders, movement disorders, and cognitive impairment.…
Meaning that the future mother will need extra care to ensure her and her unborn baby to stay as well as possible. Interestingly enough, the fact that so early in time Plato talked about high risk pregnancy results fascinating when in today’s world we find that the “odds of chromosomal problems also jump as you get older. About one in 200 babies born to women aged 40 or over have Down 's syndrome. This compares with one in 700 babies born with mums aged 35 to 39, and one in 1,500 babies born to mums aged 20 to 24”…
