Figure 1
Three-generation FECD pedigree. The proband is indicated with an arrow and symbol III-1, while the proband’s mother and grandmother are indicated by symbols II-2 and I-2, respectively. Family members diagnosed with FECD are indicated with symbols that are shaded black. The number of TCF4 trinucleotide repeats in each family member’s genome was determined by PCR amplification and DNA sequencing, and is indicated to the right of their pedigree symbol.

Clinical features of FECD pedigree. Confocal microscopy (right column) and slit lamp biomicroscopy (left column) images of affected family members. Patient I-2 (top row) demonstrated mild corneal guttae (modified Krachmer Grade 2) with endothelial cell density of 1976 cells per mm2 and rare polymegathism. Patient II-2 (middle row) demonstrated moderate corneal guttae (modified Krachmer Grade 4) with endothelial cell density of 1693 cells per mm2 and mild polymegathism. Patient III-1 (bottom row) demonstrated confluent corneal guttae (modified Krachmer Grade 6) with diffuse endothelial cell dropout.
