56 This type of analysis has already been performed for some of the uncommon mutations found in this work (R1162L, S1235R and L997F, see Discussion), while we performed frequency studies for D836Y, P1013L, P5L and D806G. Login to comment
77 By contrast, the pathogenic role of some of the uncommon mutations found (P5L, D836Y, P1013L, D806G, L997F, S1235R, and R1162L) is still a matter of debate (15, 17, 28, 32, 48-58). Login to comment
78 The P5L, D836Y, P1013L, and D806G mutations were found to be absent from the general population in the search performed in this work. Login to comment
