Albinism is caused by a lack of something.

Albinism is caused by a lack of melanin.

Albinism is a group of single-gene genetic diseases caused by mutations in different genes that cause defects in melanin or melanosomes biosynthesis. Generally, the type and amount of melanin produced by the human body determines the color of the eyes, skin and hair. Therefore, albinism patients will be unable to maintain the normal color of the human body due to congenital gene mutations. For this disease, symptomatic treatment and improvement of quality of life are the main methods.
