  • 功能：
    A cytochrome P450 monooxygenase involved in fatty acid metabolism in the eye. Catalyzes the omega-hydroxylation of polyunsaturated fatty acids (PUFAs) docosahexaenoate (DHA) and its precursor eicosapentaenoate (EPA), and may contribute to the homeostasis of these retinal PUFAs. Omega hydroxylates saturated fatty acids such as laurate, myristate and palmitate, the catalytic efficiency decreasing in the following order: myristate > laurate > palmitate (C14>C12>C16). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase).

    1. To the best of our knowledge, this study represents the largest effort to determine the genetic alterations underlying Bietti crystalline dystrophy (BCD) in Spain to date. Our results show that analysis of CYP4V2 variants is required for a reliable diagnosis of BCD. PMID: 29691984
    2. This is the first report of a homozygous R400C mutation in CYP4V2 with protein modelling showing high likelihood of enzyme dysfunction. The comprehensive long-term clinical follow-up provides insight into disease progression and highlights possible anti-inflammatory modulation of disease severity. PMID: 28698241
    3. Bietti crystalline dystrophy patients with CYP4V2 mutations showed more severe macular choroid atrophy as compared to EYS-related RP patients. These different damage patterns suggest differences in choroidal expression between CYP4V2 and EYS. PMID: 27658286
    4. In summary, we confirmed that the choroideremia-like fundus appearance of our patient was caused by the novel homozygous CYP4V2 variant. PMID: 27348340
    5. Photoreceptor outer segment and apical retinal pigment epithelium abnormalities underlie the relatively extensive retinal dysfunction observed in relatively early-stage Bietti crystalline dystrophy. Intravitreal Bevacizumab was effective in treating CNV in this setting. PMID: 27028354
    6. Expression levels of both CYP4V2 mRNA and protein were significantly reduced after treatment with peroxisome proliferator-activated receptor gamma (PPARgamma) antagonist GW9662 PMID: 28729181
    7. Nineteen missense, 4 nonsense, 2 deletion, 2 splice site, and 1 insertion-deletion mutations were identified in in patients with Bietti crystalline corneoretinal dystrophy. The age of the c.802-8_810del17insGC mutation was estimated to be 1040-8200 generations in the Chinese and 300-1100 generations in the Japanese populations. PMID: 28051075
    8. We found that the subfoveal choroidal thickness and the outer choroidal vascular area were smaller in Bietti Crystalline Dystrophy patients with CYP4V2 mutations than in age-, sex-, AL-, and logMAR VA-matched RP patients with EYS mutations or age-, sex-, and AL-matched healthy controls. PMID: 28763560
    9. Our findings broaden the spectrum of CYP4V2 mutations that cause BCD and the phenotypic spectrum of the disease in Chinese families. These results will be useful for the genetic diagnosis of BCD, genetic consultation, and gene therapy in the future. PMID: 26971461

    16. This finding suggests that the crystals in the lens of patients with Bietti crystalline corneoretinopathy may be produced in the same way as corneal or retinal crystalline deposits and therefore result from a systemic abnormality of lipid metabolism. PMID: 23793346
    17. The s identified a case of Bietti crystalline dystrophy with central and paracentral keratopathy and the molecular analysis of the causative gene in a Spanish family. PMID: 23538635

    25. REVIEW: genetic analyses have identified a wide spectrum of mutations in the CYP4V2gene from patients suffering from Bietti's crystalline corneoretinal dystrophy, and mutations in theCYP4F22 gene have been linked to lamellar ichthyosis PMID: 21540472
