On the other hand, patients with the common missense mutation E292V and a second, specific mutation such as E690K or T1114M develop pediatric interstitial lung disease (pILD), the phenotype of which is milder than that of fatal surfactant deficiency, suggesting that the E292V ABCA3 mutation is responsible for the development of pILD (4).

status: NEW29 The plasmid pEGFPN1-ABCA3 (17), which encodes ABCA3 protein fused with enhanced green fluorescent protein (GFP) at the COOH terminus (ABCA3-GFP), and its mutants containing pILD mutations (E292V, E690K, and T1114M) and other site-directed mutations (E292D, E292K, T1114S, E690D, and E690R) were generated as described previously and used for transient transfection experiment.

status: NEW178 Recently, we identified a novel compound heterozygous mutation (maternal T1114A and paternal W1148X) from a Japanese boy with respiratory distress from age 18 mo (37).

status: NEW182 In vanadate-induced nucleotide trapping by T1114S mutant protein, production of a photoaffinity-labeled intermediate during ATP hydrolysis was found to be similar to that of wild-type protein, whereas that of T1114M and T1114A mutant protein was 56 and 47% of wild-type protein, respectively (Fig. 5B, lanes 5-10, and C).
