Albinism is caused by a mutation in one of several genes. Each of these
genes provides instructions for making one of several proteins involved
in the production of melanin. Melanin is produced by cells called
melanocytes, which are found in your skin and eyes. A mutation may
result in no melanin at all or a significant decline in the amount of
melanin.
