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.

Bietti crystalline dystrophy is listed in the Online Mendelian Inheritance in Man (OMIM) catalog under the entry number 210370. It is also supported by scientific articles and publications available on PubMed.

Diagnostic tests for Bietti crystalline dystrophy may include genetic testing to identify mutations in the CYP4V2 gene. Blood tests and examination of the retina may also be conducted to confirm the diagnosis.

Other names for Bietti crystalline dystrophy include BCD, BCD1, and corneoretinal crystalline dystrophy type 2.
