Albinism
Albinism is one of the many genetic diseases affecting people today. In the several genes that produce or distribute melanin, a pigment found in the hair, skin, and iris, there may be a defect. A defect may cause an absence of melanin production, or a reduced amount of melanin production. Albinism is the result of a baby inheriting two of these defective genes, one from the father and one from the mother. The baby must inherit one defective gene from each parent in order to have albinism. The disease is autosomal recessive and is found on chromosome 11. It is usually detected at birth, the symptoms include having lighter skin and eyes, for some people their eyes may seem pink or red. This is due to the lack of pigmentation in their eyes, skin, and hair. Out of the total population, about 1 out of every 17,000 children are carriers for Albinism or have Albinism. Albinism is a lifelong disease, there is no way to cure it, only to treat it. To treat albinism, children must use lots of sunscreen and wear sunglasses because their eyes and skin suffer from light sensitivity, also known as photophobia. Many doctors prescribed glasses to correct vision problems and some children may even get eye surgery. Albinism does not affect a child's lifespan, but a form of albinism, Hermansky-Pudlak syndrome can shorten the lifespan due to lung disease or bleeding problems. For parents, they will have to get used to it, since the albinism is not going to go away. They must make sure that their children stay out of the sun as much as possible and keep going to the doctor for checkups on their vision. Also, there may be complications within the disease that result in decreased vision or blindness and skin cancer. There are three main forms of albinism, the first is called oculocutaneous albinism. About 1 in 20,000 people worldwide have oculocutaneous albinism. This is the most severe form of albinism. Children who experience this form of albinism have white or pink hair, skin, and

    In addition to genes, we also have melanin that is present in our bodies that is a determining factor in the color of our hair, skin and eyes. While everyone has melanin in their cells, the amount from person to person is not equal. The more melanin present in your skin, the darker your complexion will be. The different types of melanin present in the iris produce pigmentation there, and these factors are largely dependent…

    Some blood disorders can be prevented while there are others that are out of a person’s hands and have to live with a blood disorder for a life time. It is essential to know the causes of hereditary disease and know how to treat them. It is also important to know what can be done to “cure” other blood disorders and what preventive measures need to be taken in order to stop history from repeating itself. Iron deficiency anemia, sickle cell anemia, and purpura simplex are just a few blood disorders that people suffer from that are either inherited or can be prevented.…

    The Evolution of Skin Colour

    Melanin is the pigment in the skin that absorbs ultraviolet light and protects the skin from sun damage, so the less pigment in a person’s skin the less protection they have from ultraviolet light. So light skinned people (Caucasians), particularly those with light coloured eyes and light coloured hair are more susceptible to sun damage and skin cancer than people with more pigment in their skin. People, who have no melanin at all, like people with albinism or vitiligo, are much more susceptible to skin cancer.…

    Vitiligo is a disorder that causes the destruction of melanocytes. It has three important factors underlying this destruction. The depigmented skin has many aberrant functions such as a muted response to contact allergens, a phenomenon also seen in mice that depigment. The white skin of those with vitiligo does not form non-melanoma skin cancers although the white skin of albinos, which has a similar color as vitiligo, is highly susceptible to skin cancer.…

    There are several factors that contribute to the cause of BCC. These factors include, light colored skin, light colored eyes, blonde or red hair, overexposure to x-rays or radiation, many moles, genetics, many severe sunburns early in life, and long term daily sun exposure (Medline Plus, 2012). Individuals with light colored skin, hair, and eyes have poor tanning abilities and are more likely to have sun-damaged skin (Roewart-Hober, 2007). Radiation therapy in childhood for ringworm on a 58 year old patient caused an aggressively growing BCC that took over most of the posterior scalp (Asilian, 2005). Genetics also contribute to your likelihood of getting a BCC. A family history of skin cancer can increase your chances of having a BCC (Skelton, 2009). Also, there is several inherited and acquired skin disorders associated with BCC. These disorders include xeroderma pigmentosum, nevoid basal cell syndrome, Bazex-syndrome, Rasmussen syndrome, Rombo syndrome, and albinism (Roewert-Hober, 2007). Although there are several contributing factors to BCC, the number one cause is sun exposure and other ultraviolet…

    Moalem suggests that all humans had pale skin with dark hair all over to protect ourselves from too much sunlight. However, as the human evolved and lost a significant amount body hair, the skin, the largest organ of the body, would become exposed to the strong ultraviolet rays of the sun. Ultraviolet B, a specific type of ultraviolet light, is beneficial as it effectively converts our cholesterol into Vitamin D, which the body cannot simply live without. However, too much sunlight exposure and harmful effects quickly outnumber the beneficial ones, ranging from sunburn to skin cancer and the decrease of our body's folic acid. Thus, humans, especially those near the equator, developed a darker skin tone with the pigment melanin. While the color of the dark skin absorbs more heat and light, the melanin in the skin prevents too much of the harmful rays from penetrating the skin, protecting folic acid. However, "[dark skin] didn't evolve with a switch -- you can't turn it off when you need to whip up a batch of vitamin D." That is where the genetic mutation apolipoprotein E, or ApoE4 for short, came in. "[ApoE4] ensures that the amount of cholesterol flowing through your blood is cranked up. With more cholesterol available for conversion, dark-skinned people can maximize the use of whatever sunlight penetrates their skin." The fair-skinned Europeans of the time…

    Color blindness is usually inherited but you can get it other ways. Color blindness can also happen if physical or chemical damage is done to the eye, the optic nerve, or parts of the brain. The gene that produces photopigment is on the X chromosome. The X chromosome is sex-linked which is why color blindness usually is more dominant in males. Males have only one X chromosome. If this gene is…
