Albinism: Skin Disease

Improved Essays
Albinism is a skin disease that’s caused by little to no production of melanin. This disorder can affect vison, skin, hair and the person’s ability to tan. Certain genes in our body are responsible for making proteins that are involved in making melanin, which is produced by cells called melanocytes. Albinism is caused when a mutation occurs in one of these genes. It’s also caused by recessive inheritance. This means that a person has to inherit two copies of one mutated gene- one from each parent in order to inherit albinism. Signs of Albinism in vision occurs when the person is experiencing nystagmus which is involuntary back and forth movement of the eyes, inability for both eyes to move in unison also known as strabismus, extreme near …show more content…
Although the most common way to recognize albinism is white hair and pinkish skin, skin pigmentations can range from white to brown. For some people, skin coloration never changes, for others, melanin starts producing in their childhood and teenage years resulting in slight changes in skin color. People with albinism are more prone to getting a sunburn and having skin cancer. Hair color can range from white to brown or it sometimes depends on the person’s ethnicity. For example, Africans may have yellow or reddish hair. Like skin color hair pigmentation can change later on. Eye color in albinos varies from very light blue to brown and can possibly change with age. A person with Albinism might appear to have red eyes in some lighting because of their irises. The lack of pigment in their iris makes their eyes translucent which means that their iris can’t block light from entering the eye. So what we see is light reflected off the back of the eye and passes the …show more content…
Regardless of the type, vision impairment will always be an impact of albinism. There’s four types of Albinism: Oculocutaneous albinism (type 1, 2, and 3) , X-linked ocular, Hermansky-Pudlak syndrome and Chediak-Higashi syndrome. Oculocutaneous albinism is mainly caused by a mutation in one of four genes. People with type one OCA are born with milky-white skin, white hair and blue eyes. During their early childhood some might experience an increase melanin production and their hair might become golden brown. Sometimes it might even turn red or brown depending on their melanin production. The iris in their eyes may change color and loose its translucence. OCA type 2 tends to be most common in sub- Saharan Africans, African Americans and Native Americans. Their hair is yellow, red or sometimes auburn. Their eyes can be blue or grey, while their skin is white since birth. As time goes on, their skin may develop freckles or moles. Type 2 OCA is most common in South Africans. People with this type, usually have reddish-brown skin, red hair and brown eyes. On the other hand, X-linked ocular albinism is caused when there’s a gene mutation on the X chromosome. This occurs exclusively in males. People with this disorder, have vision problems, but their skin, hair and eye color are in the normal range or sometimes slightly lighter than other members of their family. People with Hemansky- Pudlak syndrome is a rare type of albinism which is caused

    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.…

    People with vitiligo may also have pigment abnormalities of the retina or iris of the eyes. The diagnosis of vitiligo is usually made by observation. White areas found at typical sites point to a diagnosis of vitiligo. If the diagnosis isn't certain the doctors will test for other conditions that are similar to vitiligo, such as chemical leukoderma or systemic lupus erythematosus. For treatment vitiligo can't be cured, but can be managed by using things such as skin creams and cosmetics to improve the appearance of the white areas and also prevent the normal skin around the patches from becoming darker.…

Considering that school problems are the single most common complication of NF1 that effects the patients’ everyday learning environment entirely (Tonsgard 1, School Problems), neurofibromatosis is a severe genetic disorder that cannot be cured. Neurofibromatosis patients tend to obtain learning disabilities and developmental abnormalities due to brain tumors, attention deficits, and cognitive impairments.

    Wind back the tape of life, Stephen Jay Gould once said, and the chance becomes vanishingly small that anything like human intelligence would grace the replay. Whether evolution can produce the same kinds of creatures more than once is a question that has been on more than one mind for a long time. Some biologists argue that evolution is a deterministic process, meaning that similar environments will tend to produce similar outcomes. Others think its course follows unpredictable twists and turns, and that the same starting point can lead to very difficult results. Say we rewound time, and took the history of our planet back some million years.…

    Essay On Color Blindness

    • 810 Words
    • 4 Pages

    This common form of color blindness is an X-linked recessive gene. The chromosomes given from your mother in your DNA are both X-linked and are most commonly inherited from your mother. If this is the case then it is possible that your mother might have a good chance of having color blindness herself in some form or another. If your father has the X-linked gene then it is passed down and inherited by the daughter not the son because a son cannot inherit X-linked information from his father. If a daughter gets an X-linked gene for color blindness from both her mother and father then she will not only inherit the disorder but also be a carrier of the disorder as well.…
