COL17A1 and corneal dystrophy: Additional evidence of the pathogenic role of the c.3156C> T variant in COL17A1 in ERED has been provided by Oliver and colleagues.[13, 14] After a genome-wide association study in a New Zealand family with a corneal dystrophy associated with early onset of recurrent corneal erosions demonstrated a signal on chromosome 10, exome sequencing identified candidate variants in three genes, including COL17A1. Screening of COL17A1 in this family and in two other families with a similar phenotype confirmed segregation of the c.3156C>T variant with the affected phenotype in each family.
