Abstract
To detect potential mutation in a large Chinese pedigree affected with congenital corneal dystrophy. Two patients from the pedigree were subjected to whole exome sequencing to determine the candidate gene. Suspected mutation was verified in 13 additional members by directional Sanger sequencing. Ccorrelation between genotype and phenotype was explored. A missense mutation, c.1877A>C (p.His626Pro), was detected in exon 14 of the TGFBI gene in 8 patients from the pedigree, but not in five unaffected members and 100 unrelated healthy controls. Respectively, the mutation was predicted as "affecting protein function", "probably damaging" and "disease causing" by SIFT, PolyPhen-2 and MutationTaster. The c.1877A>C mutation of the TGFBI gene probably underlies the disease in this pedigree.
