Three-Dimensional Structural Prediction of the SDHD Protein. Three-dimensional structural models of the SDHD protein generated using AlphaFold and visualized with PyMOL. Panel (a) illustrates the wild-type SDHD protein structure, while panel (b) shows the structural impact of the p.R22X mutation, indicating the significant loss of a portion of the amino acid sequence due to this pathogenic variant
