It may be an article of faith among geneticists that knowledge is power in cases like Gessen's, but she reminds us that it is also terror: More than eight years after testing for the Huntington's mutation was available, only 300 people in the United States completed the screening process.
Inhibition and/or binding data [47, 49] (including variation of ATP concentration and by single site mutation) are available from a variety of protein forms and assay formats [40, 82, 91, 92, 105 116].
Furthermore, no photographic or digital image documentation of human cataracts caused by the R120G mutation is available.
Currently, there are six known examples of inherited neurological/neuromuscular diseases of cattle where the molecular basis has been elucidated and gene tests for selection against the deleterious mutation are available.
Given that the current cost of whole genome sequencing remains high for routine analysis of large populations, techniques that allow targeted sequencing of defined genomic regions are valuable tools to facilitate the search for causative mutations in genetic disease cases when prior information regarding the location of a mutation is available.
Consequently, no information on the potential vemurafenib response for this mutation was available.
45 Data relevant to the long-term outcomes of patients with the HNF1A mutation are available from two papers: Steele et al 2010 46 and Isomaa et al 1998.
Other frequently-occurring mutations at residues Y220, G245, R175 and R273 showed similar survival curves as nonsense mutations, and very few cases with the R249S mutation are available for further analysis.
As no data on the effect of an L. monocytogenes addB null mutation are available, it is unclear which physiological functions may be affected by nonsynonymous mutations in this gene.
Cohen says a simple genetic test for the mutation is available and could be considered reasonable to add to newborn screening for metabolic disorders, so as to avoid aminoglyosides if at all possible in those carrying this mutation.
