Abstract
PURPOSE: The aim of this study was to report a lattice corneal dystrophy (LCD) family with a novel mutation of A620P in the TGFBI gene, its long-term treatment, follow-up data, and related pathologic findings. METHODS: A total of 28 family members were clinically examined, and blood samples or buccal epithelial cells were taken for DNA analysis. All exons from the entire TGFBI gene coding region were analyzed for mutations in 3 affected members. Exon 14 was amplified in other family members and in 100 normal Korean persons as control. Corneal tissues from 1 affected family member were examined using light and electron microscopy. RESULTS: Clinical examination revealed relatively late-onset LCD with asymmetric progression and recurrent corneal erosion. The affected family members have been treated with penetrating keratoplasty, deep lamellar keratoplasty, and phototherapeutic keratectomy for up to 19 years. Screening of the TGFBI gene revealed a novel A620P mutation, which was found in all affected members. The amyloid origin of deposits was confirmed by Congo red and was also partially stained with Masson trichrome. Although there were no electron-dense bodies as in granular dystrophy, transmission electron microscopy demonstrated that the stromal deposits were not homogenous and contained a variety of constituents with different electron densities. CONCLUSIONS: We present the characteristics and surgical treatment of corneas with a novel A620P mutation in TGFBI showing LCD type IIIA with hyaline component.
