AIM: To analyze mutations in transforming growth factor beta-induced (TGFBI) gene in a Chinese pedigree with Reis-Bücklers corneal dystrophy (RBCD, also known as GCD3). METHODS: In a five-generation Chinese family, eight members were identified with RBCD and the rest were unaffected. All members of the family underwent complete ophthalmologic examinations. Exons of TGFBI were amplified by polymerase chain reaction, sequenced, and compared with a reference database. RESULTS: A single heterozygous C>T (R124C) point mutation was found in exon 4 of TGFBI in all the affected members of the pedigree, but not in the unaffected members. CONCLUSION: R124C which was a known mutation for lattice corneal dystrophy type I, segregated with the RBCD in this pedigree. This elucidated the correlation between genotype and phenotype in a Chinese family of RBCD.
