Four cases showed a single mutational event and 4 revealed several mutations in more than one exon.
While p53 contains inactivating mutations in more than half of HPV-negative oral cancers, it is rarely mutated in HPV-positive SCCHN [ 8].
ALS is associated with genetic mutations in more than 50 different genes, but, as is the case for Alzheimer's, all of these cause inherited forms of the disease, which account for just 10-15% of cases.
Mutations in more than 40 genes have been identified to date in CMT.
The statistics of library with mutations in more than 20 amino acids can be calculated easily.
Overall, his team could detect mutations in more than 80% of tumor plasma samples.
Mutations in more than 80 genes cause monogenic disorders that include severe skin fragility, myopathies, neurodegeneration, and premature ageing, and contribute to polygenic disorders including liver and inflammatory bowel disease.
Other genes, i.e., TP53BP1, CSMD1, TTC28, DLK2, and KTN1, were also found to harbor somatic mutations in more than one individual, possibly indicating a previously undescribed association with UM pathogenesis.
Mutations in more than 200 different genes are known to cause many of these disorders and in less obvious disorders several genes may have to be sequenced in order to identify the correct diagnosis in a patient.
Inheritance of germline mutations in more than 2,800 genes cause documented genetic disease (see OMIM database: http://www.ncbi.nlm.nih.gov/omim/).nih.gov/omim/
Mutations were only found in the coding regions of the pyrF and pyrE2 genes and a number of mutants had mutations in more than one gene (Table 1).
