The <jats:italic>GAA<\/jats:italic> gene is located on chromosome 17 (17q25.3), the GAA protein consists of 952 amino acids; of which 378 amino acids (347\u2010726) falls within the catalytic domain of the protein and comprises of active sites (518 and 521) and binding sites (404, 600, 616, and 674). In this study, we used several computational tools to classify the missense mutations in the catalytic domain of GAA for their pathogenicity and stability. Eight missense mutations (R437C, G478R, N573H, Y575S, G605D, V642D, L705P, and L712P) were predicted to be pathogenic and destabilizing to the protein structure. These mutations were further subjected to phenotyping analysis using SNPeffect 4.0 to predict the chaperone binding sites and structural stability of the protein. The mutations R437C and G478R were found to compromise the chaperone\u2010binding activity with GAA. Molecular docking analysis revealed that the G478R mutation to be more significant and hinders binding to the DNJ (Miglustat) compared with the R437C. Further molecular dynamic analysis for the two mutations demonstrated that the G478R mutation was acquired higher deviation, fluctuation, and lower compactness with decreased intramolecular hydrogen bonds compared to the mutant R437C. These data are expected to serve as a platform for drug design against Pompe disease and will serve as an ultimate tool for variant classification and interpretations.<\/jats:p>","DOI":"10.1002\/jcb.27624","type":"journal-article","created":{"date-parts":[[2018,10,5]],"date-time":"2018-10-05T14:56:28Z","timestamp":1538751388000},"page":"3491-3505","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["A computational method to characterize the missense mutations in the catalytic domain of GAA protein causing Pompe disease"],"prefix":"10.1002","volume":"120","author":[{"given":"D","family":"Thirumal Kumar","sequence":"first","affiliation":[{"name":"Department of Integrative Biology School of Bio Sciences and Technology, Vellore Institute of Technology Vellore Tamil Nadu India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryam","family":"Umer Niazullah","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences College of Health and Sciences, Qatar University Doha Qatar"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sadia","family":"Tasneem","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences College of Health and Sciences, Qatar University Doha Qatar"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E","family":"Judith","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology School of Bio Sciences and Technology, Vellore Institute of Technology Vellore Tamil Nadu India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Susmita","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology School of Bio Sciences and Technology, Vellore Institute of Technology Vellore Tamil Nadu India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5971-8290","authenticated-orcid":false,"given":"C","family":"George Priya Doss","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology School of Bio Sciences and Technology, Vellore Institute of Technology Vellore Tamil Nadu India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E","family":"Selvarajan","sequence":"additional","affiliation":[{"name":"Department of Genetic engineering School of Bioengineering, SRM Institute of Science and Technology Kattankulathur Chennai India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8838-6638","authenticated-orcid":false,"given":"Hatem","family":"Zayed","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences College of Health and Sciences, Qatar University Doha Qatar"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,10,3]]},"reference":[{"key":"e_1_2_7_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(18)53985-5"},{"key":"e_1_2_7_1_3_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M404008200"},{"key":"e_1_2_7_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pedneo.2013.03.009"},{"key":"e_1_2_7_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ncl.2014.04.010"},{"key":"e_1_2_7_1_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjpo\u20102017\u2010000182"},{"key":"e_1_2_7_1_7_1","doi-asserted-by":"publisher","DOI":"10.1089\/dna.1990.9.85"},{"key":"e_1_2_7_1_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5200367"},{"key":"e_1_2_7_1_9_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2007\u20102222"},{"key":"e_1_2_7_1_10_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.76.9.4526"},{"key":"e_1_2_7_1_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-1809.1979.tb00661.x"},{"issue":"10","key":"e_1_2_7_1_12_1","first-page":"49374945","article-title":"Biosynthesis of lysosomal enzymes in fibroblasts.
