What causes ocular albinism type 1?

Ocular albinism type 1 is caused by mutations in the GPR143 gene.[1] This gene gives the body instructions for making a protein that plays a role in pigmentation (coloring) of the eyes and skin. It helps control the growth of melanosomes, which are structures inside cells that make and store a pigment called melanin. Melanin also plays a role in vision in the retina. Mutations in the GPR143 gene can affect the protein's ability to do its job. As a result, melanosomes in skin and retinal cells can grow abnormally large, contributing to the signs and symptoms of the condition.[2] In rare cases, the genetic cause of this condition is unknown.
