The table shows the ten most abundant proteins in the amyloid deposits and periamyloid corneal tissue from the LCD type 1 variant, and healthy corneal stroma listed according to their mol % values. The different types of collagen are ranked according to the collagen chain with the highest emPAI-based molar fraction. The collagen chain species are indicated in brackets after the mol % values. Proteins shown in bold have at least a twofold increase in molar fraction compared to the healthy stroma.
