In principle, there are several mechanisms by which a noncoding trinucleotide repeat (TNR) expansion in TCF4 could lead to the development of FECD, including a direct effect on TCF4 expression, production of toxic repeat-associated non-ATG (RAN) translation products and changes in RNA splicing 12 Other genes including solute carrier family 4, sodium borate transporter, member 11 (SLC4A11, MIM 610206), transcription factor 8 (TCF8, MIM 189909), lipoxygenase homology.

12 Other genes including solute carrier family 4, sodium borate transporter, member 11 (SLC4A11, MIM 610206), transcription factor 8 (TCF8, MIM 189909), lipoxygenase homology. 25, 49 In vitro FECD models showed that FECD cells rapidly deposit high amounts of fibronectin on the surface of their basement membrane. FECD can be inherited as an autosomal dominant trait with genetic heterogeneity

The third outcome was progression of FECD determined by an increase in CCT of 5% or more (sustained over at least 2 consecutive examinations on different days or subsequently associated with clinically definite edema) measured by using ultrasonic pachymetry (Pachette 2; DGH Technology, Exton, PA) compared with that obtained at the enrollment.
240221_a74324_03.jpg. (2001) conducted a genomewide search of a 3-generation family with early-onset FECD and identified a critical region of 6 to 7 cM at chromosome 1p34.3-p32, which includes the COL8A2 gene.COL8A2 encodes a short-chain collagen which is a component of endothelial basement membranes and which represented a strong candidate gene. Purpose: CTG trinucleotide repeat (TNR) expansion in an intron of the TCF4 gene is the most common genetic variant associated with Fuchs' endothelial corneal dystrophy (FECD)
