Comparative Analysis and 3D Modeling of Missense Variants in the HEXA Gene
This study resolves diagnostic discrepancies for uncertain HEXA missense variants associated with Tay-Sachs disease by correlating clinical and machine-learning classifications with 3D structural modeling, demonstrating that buried core residues induce higher rotamer strain and reduced flexibility compared to surface-exposed variants, thereby validating structural analysis as a tool for improving variant interpretation and therapeutic development.
