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. WebJul 21, 2024 · Duchenne muscular dystrophy is the most common neuromuscular genetic disorder. This review describes the identification of the cause of the disorder in the late 1980s—dystrophin deficiency—and the emerging therapeutics enabled by increased understanding of dystrophin structure and function.

Dystrophin - Wikipedia

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… WebDystrophin is predominantly hydrophilic throughout its entire length and 31% of the amino-acids are charged (i.e. Arg, Asp, Glu, His and Lys). A "Chou and Fasman" prediction of secondary structure reveals a very high potential for an alpha-helical formation over the majority of the sequence. Dystrophin can be separated into four domains:
