The p. Arg555Trp mutation of the TGFBI gene was associated with TBCD, which revealed a novel phenotype-genotype correlation within the mutational spectrum of phenotypically diverse corneal dystrophies.

Two patients from one pedigree (a 29-year-old woman and 58-year-old man) with Thiel-Behnke corneal dystrophy (Arg555Gln [R555Q] heterozygous missense mutation of human transforming growth factor beta-induced [TGFBI] gene) and 3 patients from one pedigree (a 70-year-old woman, 58-year-old man, and 14-year old man) with Reis-Bücklers corneal dystrophy (Arg124Leu [R124L] heterozygous missense mutation of the TGFBI gene) were examined.
For example, lattice dystrophy types I and IIIA, granular corneal dystrophy types I, II (Avellino dystrophy), and III (Reis-Bucklers dystrophy), and Thiel-Behnke corneal dystrophy are the result of mutations in BIGH3.
