Bietti crystalline dystrophy

Bietti crystalline dystrophy is a rare genetic disorder associated with mutations in the CYP4V2 gene. It is also known as corneoretinal crystalline dystrophy or Bietti corneoretinal dystrophy.

The CYP4V2 gene encodes an enzyme called cytochrome P450 4V2, which is responsible for breaking down fatty acids in the retina. Mutations in this gene can lead to the accumulation of fatty deposits known as crystals in the cornea and retina, causing progressive vision loss.
