Purpose:To report TGFBI gene mutations in the Chinese with lattice corneal dystrophy. Cases and Methods:Samples were obtained from the circulating blood of 82 persons. The series comprised 26 affected and 6 unaffected persons in 11 pedigrees,and 50 normal persons. Genomic DNA in the samples was then amplified by polymerase chain reaction and was directly sequenced. Results:R124C was present in 14members of 6 pedigrees. H626R was present in 3members of 2 pedigrees. As novel findings,V505D was present in 8members of one pedigree,and P542R was present in 2members of 2 pedigrees. No mutation was present in 50 normal persons. Conclusion:The incidence of R124C was 54.5% in Chinese patients. This rate was comparable with that in the Japanese(44.4%). Presence of H626R in 2 Chinese pedigrees are of interest,since it was found in Europeans,Indians and Vietnamese but not in the Japanese.
