Editor: Bolysbek Dana Author: Tulkibaeva Nursulu Eye color is a characteristic determined by the pigmentation of the iris and the scattering of light. Until now, it was believed that eye color is regulated by only one or two genes, and brown eye formation of eye color. Scientists led by King's College London and Erasmus University Rotterdam the study analyzed the genetics of almost 195,000 people from Europe and Asia, identifying 50 new genes involved in the formation of eye color. There are eye diseases that occur at certain levels of pigmentation. For example, in pigmented glaucoma, with this disease, the pigment melanin is washed out, and with ocular albinism, its synthesis is disrupted. These diseases are rare, but the disclosure of the mechanisms of their occurrence plays an important role. Research from King's College London and Erasmus University Rotterdam takes us a step closer to understanding the genetics of eye color and studying eye diseases in more detail.
