a Domain structure of COL1A1 protein with p.Gly22Arg substitution in the signal peptide highlighted in blue. b Prediction of the cleavage site probability of the wt COL1A1 sequence and the p.Gly22Arg substitution using the SignalP algorithm. The algorithm predicts a strong reduction of the cleavage site probability (from 0.956 to 0.319) for the p.Gly22Arg substitution. The predicted cleavage site for the Gly22Arg substitution with the highest probability is at a different position (between Gly30 and Gln31). A black arrow indicates the position of the wt signal peptide cleavage site; n-region: N-terminal region; h-region: hydrophobic region; c-region: cleavage region (Color figure online)
