Genetic and Chromosomal Abnormalities

There are many genetic and chromosomal abnormalities that ail much of our population today. The three that I chose to discuss, not only peak my interest, but are also disorders that I plan to work with in the future: Klinefelter Syndrome, Fragile X Syndrome, and Downs Syndrome. All three disorders impair those that they affect, in mental, cognitive and physical aspects of their lives. Thankfully today we have a lot of helpful information that categorizes, assists and educates people on these disorders. Although these three disorders differ from each other, they also share a large amount of similar characteristics, that unite those that suffer from them.

Klinefelter Syndrome also known as “47 XXY Syndrome” is a chromosomal abnormality that only affects males, 1 out of every 1,000. These males are born with at least one extra X (sex) chromosome. The symptoms include: learning disabilities, personality impairment, enlarged breast tissue, small/firm testis, diminished (pubic, axillary, and facial) hair, tall stature, abnormal body proportions (long legs, small trunk), and sexual dysfunction. Males that have more than one extra X chromosome often suffer from more severe physical and cognitive symptoms, than those with just one extra X chromosome. There is no known cure or specific prevention measures for this disorder, but there are some symptoms such as; delayed puberty, hair growth, and sex drive, that can be treated medically.

Socially, it is easier on males with Klinefelter Syndrome if they are diagnosed at a younger age, this eliminates the struggle of not understanding what is wrong and allows for the treatment of certain symptoms. The earlier treatment helps those ailed by this disorder to lead a more “normal” childhood, adolescence and eventually adulthood. The majority of the issues occur throughout childhood

    Down’s syndrome is a disorder caused by a fault of the chromosomes; the pieces of DNA containing the outline for the human body. Normally a person has two copies of each chromosome but a person with Down syndrome has three copies. The extra DNA produces the physical and mental sort of Down syndrome, which include a small head that is flattened in the back, slanted eye, extra skin folds at the corners of the eyes, small ears, nose and mouth, short height, small hands and feet and some degree of mental disability.…

    Klinefelter's Syndrome is a genetic condition that is only found in males and the male is born with an extra copy of the X chromosome. It was first diagnosed by Dr. Harry Klinefelter and his coworker in 1942. They did a group research of men who had the symptoms of Klinefelter syndrome. By late 1950, Dr.Klinefelter discovered that the men with Klinefelter syndrome had an extra sex chromosome making them XXY instead of a normal male XY. “Klinefelter’s syndrome occurs in about 1 in 500-1000 male births and over 3,000 males are affected yearly.” (Fedor, 2013)…

    A biological explanation states that gender dysphoria is caused by abnormal prenatal exposure to androgens (male hormones). Some genetic conditions can cause discrepancy between hormones and genetic sex (e.g. Cognitive Adrenal Hyperplasia) occurs when genetic females have high levels of androgens which cause them to develop a small penis. The outcome of this may be gender dysphoria as individuals suffer confusion about their gender…

    Enzymes are important to the body and the development of our metabolisms. Enzymes are what makes the body get the proper energy source for our growth and development. If enzymes are lacking or missing it can cause diseases and birth defects. There are many different types of diseases that come from having a defective enzyme. Among the many, Lysosomal storage disorder (LSD) is an inherited autosomal recessive gene disorder. Meaning that it is an inherited disorder that has come from both parents. (Lysosomal Storage Disorders, 2003-2006) This specific disorder is when the body is missing the enzymes that have the ability to recycle cellular waste. The role of the enzyme missing from this disorder, has the function of breaking down the more complex…

    It may make us wince with discomfort to hear such a controversial question raised. Sometimes people imply that I shouldn’t even bother responding to questions like this. However, I prefer to do so because I know there are some people out there who want to be or already are in interracial relationships, and have these sorts of fears, worries and concerns that they’d like express and hear others thoughts on, but can’t find the proper place, person or way to ask without being misunderstood or coming across as offensive. Sometimes it’s important to discuss that “elephant in the room” and spread enlightenment through the exchange of ideas.…
