WebDystrophin is a critical part of the dystrophin-glycoprotein complex (DGC), which plays an important role as a structural unit of muscle. In DMD, both dystrophin and DGC proteins are missing, which ultimately leads to the death (necrosis) of muscle cells. People with DMD have less than 5% of the normal quantity of dystrophin needed for healthy ... WebJun 24, 2015 · Mutations in dystrophin have been extensively cataloged, providing remarkable structure-function correlation between predicted protein structure and clinical outcomes.

"Dystrophin is a rod-shaped cytoplasmic protein, and a vital part of a protein complex that connects the cytoskeleton of a muscle fiber to the surrounding extracellular matrix through the cell membrane. This complex is variously known as the costamere or the dystrophin-associated protein complex (DAPC). Many muscle proteins, such as α-dystrobrevin, syncoilin, synemin, sarcoglycan, dystr… " - Dystrophin structure

WebDystrophin may also play a role in chemical signaling within cells. Mutations in the DMD gene alter the structure or function of dystrophin or prevent any functional dystrophin from being produced. Muscle cells without enough of this protein become damaged as muscles repeatedly contract and relax with use. The damaged fibers weaken and die … WebIn a 12-year-old boy with asymptomatic dystrophinopathy (see 300376), Yagi et al. (2003) identified a point mutation in intron 2 of the DMD gene (300377.0083) that creates an AG dinucleotide consensus sequence for a splicing acceptor site predicted to produce a novel exon structure that is then incorporated into dystrophin mRNA.
