Background: Out of the eleven MPS disorders, MPS I includes three syndromes, of which the first, named Hurler syndrome, affects the most. Methods: Several in silico tools were used, such as ConSurf (73 variants), Mutation Assessor (69 variants), PredictSNP, MAPP, PhDSNP, Polyphen-1, Polyphen-2, SIFT, SNAP, PANTHER, MetaSNP (24 variants); Missense 3D-DB (11 variants) and AlignGVGD (eight variants) for physicochemical properties; and I-Mutant, Mupro, CUPSAT, and INPS for stability predictions (four variants). Results: A molecular docking study was performed for the two variants: L238Q and P385R scored \u22127.22 and \u22127.05 kcal\/mol, respectively, and the native scored \u22127.14 kcal\/mol with IDR as the ligand. Molecular dynamics anticipated how these molecules fluctuate over a period of 100 nanoseconds. Conclusions: Alpha-L-iduronidase enzyme has a critical role in the lysosomal degradation of glycosaminoglycans. According to the comparative analysis of the three structures by MDS, P385R had the least stability in all aspects of the plots. Our study demonstrates that the mutation significantly alters protein stability and binding efficiency with the ligands.<\/jats:p>","DOI":"10.3390\/ph18060922","type":"journal-article","created":{"date-parts":[[2025,6,19]],"date-time":"2025-06-19T09:57:48Z","timestamp":1750327068000},"page":"922","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Prognostic Modeling of Deleterious IDUA Mutations L238Q and P385R in Hurler Syndrome Through Molecular Dynamics Simulations"],"prefix":"10.3390","volume":"18","author":[{"given":"Madhana","family":"Priya Nanda Kumar","sequence":"first","affiliation":[{"name":"Department of Biotechnology, Faculty of Biomedical Sciences & Technology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai 600116, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esakki","family":"Dharsini Selvamani","sequence":"additional","affiliation":[{"name":"Department of Bioinformatics, Bishop Heber College, Tiruchirapalli 620017, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Archana","family":"Pai Panemangalore","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biomedical Sciences & Technology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai 600116, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sidharth","family":"Kumar Nanda Kumar","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biomedical Sciences & Technology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai 600116, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasundra","family":"Vasudevan","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biomedical Sciences & Technology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai 600116, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9508-8097","authenticated-orcid":false,"given":"Magesh","family":"Ramasamy","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biomedical Sciences & Technology, Sri Ramachandra Institute of Higher Education and Research (DU), Chennai 600116, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1038\/s41572-018-0025-4","article-title":"Lysosomal storage diseases","volume":"4","author":"Platt","year":"2018","journal-title":"Nat.
