Description
DiaPlexQ™ 5 types Corneal Dystrophy (CD) Genotyping Kit
Real-Time PCR based assay system for the genotyping of the SNP of codon 124, 555(exon4) in TGFβ1 related to avellino corneal dystrophy
CE-IVD
The TGFβI gene is firstly appear at the 5q31 chromosome related corneal dystrophy on the corneal epithelium. Morbid cover of TGFβI is detected from the cornea, so we suppose the cause of disease related on 5q31 chromosome. There are Avellino Corneal Dystrophy(ACD), Reis-Buckler’s Corneal dystrophy(RBCD), lattice Corneal dystrophy(LCD), granular Corneal dystrophy(GCD type1), Thiel-Behnke Corneal Dystrophy(TBCD) which are related with chromosome 5q31 and TGFβI gene. The IC3D had classified the diseases as category1. Although there are some remedies like sublayer corneal transplantation and penetrating keratoplasty, there are many cases that the disease recur after the operation. In case of heterozygote people perform the laser surgery such as like LASEK or LASIK. There is possibility of lose eye sight caused by corneal opacity. The Coneal Dystrophy genetic diagnosis before LASEK, LASEK surgery is kind of essential clinical test.
