Abstract: 
Objective: To investigate gene mutations associated with three different types of corneal dystrophies (CDs), and to establish a phenotype-genotype correlation. Methods: Two patients with Avellino corneal dystrophy (ACD), four patients with lattice corneal dystrophy type I (LCD I) from one family, and three patients with macular corneal dystrophy type I (MCD I) were subjected to both clinical and genetic examinations. Slit lamp examination was performed for all the subjects to assess their corneal phenotypes. Genomic DNA was extracted from peripheral blood leukocytes. The coding regions of the human transforming growth factor β-induced (TGFBI) gene and carbohydrate sulfotransferase 6 (CHST6) gene were amplified by polymerase chain reaction (PCR) and subjected to direct sequencing. DNA samples from 50 healthy volunteers were used as controls. Results: Clinical examination showed three different phenotypes of CDs. Genetic examination identified that two ACD subjects were associated with homozygous R124H mutation of TGFBI, and four LCD I subjects were all associated with R124C heterozygous mutation. One MCD I subject was associated with a novel S51X homozygous mutation in CHST6, while the other two MCD I subjects harbored a previously reported W232X homozygous mutation. Conclusions: Our study highlights the prevalence of codon 124 mutations in the TGFBI gene among the Chinese ACD and LCD I patients. Moreover, we found a novel mutation among MCD I patients.
