What gene causes albinism?
Ocular albinism (OA1) is caused by a genetic defect on chromosome 11 of the GPR143 gene. Oculocutaneous albinism type 2 (OCA2 or P gene albinism) results from a genetic defect on chromosome 15 in the P protein that helps the tyrosinase enzyme to function. Oculocutaneous albinism type 3 (OCA3) is rarely described and results from a genetic defect on chromosome 9 in TYRP1, a protein related to tyrosinase. Oculocutaneous albinism type 4 (OCA4) results from a genetic defect in chromosome 5 at position 13.3, in the SLC45A2 protein that helps the tyrosinase enzyme to function.
What seems to produce more melanin pigmentation in the extremities of Siamese cats?
Albinism is a mutation in the TYR gene, responsible for the enzyme tyrosinase. Tyrosinase, in turn, is necessary for the production of melanin, or dark pigmentation.See the related link for further information.
What is albinism the scientific term?
One would define albinism as either a complete or partial absence of skin, hair, and eye pigment. This is due to the deficiency of an enzyme called tyrosinase, which is involved in the production of melanin.
What is the missing protein that makes people albino?
The missing protein in people with albinism is called tyrosinase. Tyrosinase is an enzyme that plays a key role in the production of melanin, the pigment that gives color to the skin, hair, and eyes. Its absence or low activity in individuals with albinism leads to a lack of melanin production, resulting in their characteristic pale skin, hair, and eyes.
How is the condition of albinism?
that is lack of pigmentation on the skin (melanin). for more information visit the related links box below for the wikipedia article on albinism
What enzyme converts tyrosine into melanin?
The enzyme responsible for converting tyrosine into melanin is tyrosinase. Tyrosinase catalyzes the reactions that lead to the production of melanin, the pigment responsible for skin, hair, and eye color.
What food contains tyrosinase?
I looked it up at Answers.com (http://www.answers.com/tyrosinase?cat=health) Appears that TYROSINASE is contained in some fruits and vegetables (like apples, or potatoes; the entry in Answers.com also explains that this enzyme is responsible for the dark colour produced when cut raw food is exposed to air.
Is albinism common?
albinism is common.
What are some demographics of albinism?
What are the demographics of albinism:
What is ocular albinism?
Ocular Albinism is a type of albinism that affects mostly vision. It commonly comes with the lack of melanin in the skin that occurs in regular albinism.
