Lattice dystrophies are characterized by the build up of protein fibers (i.e., amyloid) in the stroma. Symptoms may include corneal erosions, decreased vision, photosensitivity, and eye pain. Most cases of lattice dystrophy are caused by mutations in the TGFBI gene.
Lattice dystrophy type 1 is the most common type of lattice dystrophy. It is characterized by fine rod-like glassy opacities (i.e., lattice lines) near the front of the stroma. The opacities often appear in the first or second decade of life and worsen over time. Recurrent corneal erosions are common, which may result in decreased vision, photosensitivity, and eye pain. It is inherited in an autosomal dominant pattern.
GeneTests.org lists a laboratory that is offering clinical genetic testing for this condition. In general, clinical genetic tests may be ordered to help diagnose a person or family, to confirm a diagnosis, and/or to aid in decisions regarding medical care or reproductive issues. We recommend that you talk to your health care provider or a genetic professional to learn more about your testing options, including the costs and benefits of testing.
