Most of the deleterious mitochondrial mutations are heteroplasmic, meaning that wild type and mutated forms of mtDNA coexist in the same cell.
We then mutated threonine residues into alanine to make single- or double-site mutated forms of EGL3.
Mutations in LGI1 cause heritable epilepsies in humans, and one of these mutated forms of LGI1 fails to bind ADAM22 [ 29, 72].
In 1999, Ruthie Amir and Huda Zoghbi at the Baylor College of Medicine discovered that mutated forms of this gene are the cause of Rett syndrome.
Mutated forms of Ras are found in 30% of human cancers including a substantial proportion of pancreatic and colon adenocarcinomas.
King, M. C., Raposo, G. & Lemmon, M. A. Inhibition of nuclear import and cell-cycle progression by mutated forms of the dynamin-like GTPase MxB.
Drugs such as Herceptin and Gleevec have successfully targeted the mutated forms of these genes, as well as their counterparts, tumor suppressor genes.
Because tumor cells are mutated forms of the body's own cells, not an invading pathogen, they do not usually elicit a strong immune response.
Again studying DNA from colon cancer cells, Vogelstein eventually identified three tumour-suppressor genes, p53 (1989), DCC (1990), and APC (1991), mutated forms of which were found in the tumour cells.
This paper shows that mutated forms of human XRCC1, a scaffold protein involved in DNA single-strand break repair, are associated with ocular motor apraxia, axonal neuropathy, and progressive cerebellar ataxia.
