3 Results We identified 1 infant homozygous for the g.1549C > GAA mutation (121ins2) in SFTPB for whom only the mother was heterozygous and 3 infants homozygous for mutations in ABCA3 (p.K914R, p.P147L, and c.806_7insGCT) for whom only the fathers were heterozygous. Login to comment
54 Sequence analysis of ABCA3 revealed a homozygous C>T transition in codon 147 that changes a proline to leucine (c.440C>T; p.P147L) and is predicted to be deleterious by SIFT and Polyphen. Login to comment

229 In contrast, a second group of lung disease-associated mutations that are proximal to N-glycan sites and/or that could profoundly alter the structural makeup of the loop such as P147L (23) and R43L (6, 20) may adversely influence glycosylation and subsequent ABCA3 biosynthesis. Login to comment
