What heredity is albinism?

summary

Albinism is a hereditary leukoplakia caused by melanin deficiency or synthesis disorder of skin and accessory organs due to tyrosinase deficiency or dysfunction. The patient's retina is pigmented, and the iris and pupil are pale pink, afraid of light. What heredity is albinism? Next, I'd like to share my views with you.

What heredity is albinism?

Albinism is usually inherited by autosomal recessive inheritance, which is mostly caused by close relative marriage. That is to say, both parents of the patient carry the albinism gene and do not develop the disease themselves. If both husband and wife pass the disease causing gene to their children at the same time, they will get sick, and men and women in their children have the same chance of getting sick. The probability of this situation is 1 / 4.

There is a type of albinism characterized by eye damage, known as eye albinism, which is characterized by X-linked recessive inheritance. It is only when the albinism gene carried by the mother is passed on to the son that the mother gets sick, and when it is passed on to the daughter, it is generally not. The probability of this transmission is 1 / 2. This type of albinism accounted for a relatively small proportion in all types of albinism. About 70 people with normal phenotypes have a heterozygous albino gene.

To carry out some symptomatic treatment, so that the condition can be weakened a lot, some of the later related treatment and nursing is relatively easy a lot. Try to avoid strong sunlight. You can wear sunshade hat and long sleeve clothes to minimize outdoor activities under strong light, which can lead to the possibility of solar dermatitis and even skin cancer;
