Dystrophin gen mutation
WebIn this study, we analyzed the mutational profile of the dystrophin gene in 69 Colombian patients affected with DMD/BMD. The results revealed mutational heterogeneity in the DMD gene, as expected, with 57 different mutations in 69 patients. Large deletions were the genetic cause of 58% of the cases. WebTo verify whether MGNs could be used to restore the normal reading frame of a dystrophin gene with a frameshift mutation, we inserted in a plasmid coding for the dog micro …

http://compbio.berkeley.edu/people/ed/rust/Dystrophin.html WebThe dystrophin gene is the largest gene identified so far, covering more than 2.5 megabases (Mb), and contains at least 79 exons; the high spontaneous mutation rate is a reflection of the large gene size. Dystrophin is primarily expressed in skeletal, cardiac, and smooth muscle cells, with smaller amounts expressed in the brain and retina.

WebJul 2, 2024 · Duchenne muscular dystrophy (DMD) is a rare genetic disorder caused by mutations in the DMD gene resulting in premature termination codons (PTC) and, therefore, the absence of functional dystrophin protein. Lack of dystrophin is responsible for instability of skeletal muscle fibers and cardiomyocytes during contraction, leading to …
