Question
3. A 72 year old man, Otto, has very poor vision caused by a network of protein fibers that form a lattice-like blockage in his eyes. His vision began failing when he was in his thirties. The man's 42-year old daughter Barbie developed vision loss and has the same defect as her father, the autosomal dominant condition lattice corneal dystrophy. Although symptoms generally begin after age 30, the first strands of protein in the eye can be seen by an ophthalmologist by the late teens. A mutation in the gene for a protein called gelsolin, which binds to the contractile protein actin, causes lattice corneal dystrophy. Gelsolin clears actin away after injury or inflammation. Compare the wild type or "normal" and Otto's family DNA. (10 Pts) A.
