Brunner, M.D., Ph.D., Joris A. Veltman, Ph.D., and Lisenka E.L.M. Vissers, Ph.D.: Diagnostic Exome Sequencing in Individuals with Severe Intellectual Disability Severe intellectual disability, which is referred to as cognitive impairment or mental retardation also, affects 0 approximately.5 percent of the population in Western countries1,2 and represents an important health burden.
Primary or secondary resistance to imatinib takes place in around 20 to 30 percent of patients with newly diagnosed chronic-phase CML.3,6 Second-era tyrosine kinase inhibitors, nilotinib and dasatinib, are available for the treating patients in whom level of resistance or intolerance to imatinib develops; these two medications can induce a significant cytogenetic response in 35 to 63 percent of such sufferers.7-10 However, for patients with principal or secondary resistance to nilotinib or dasatinib, whether their disease is usually diagnosed or imatinib-resistant, no approved treatment is available currently. A significant mechanism of level of resistance is definitely mutation of the BCR-ABL kinase domain.11,12 Probably the most common mutations, which exists in up to 20 percent of patients with resistance to tyrosine kinase inhibitors,12-17 is the so-called gatekeeper T315I substitution,18 which blocks access of the medication to the enzyme’s ATP-binding site and confers a high degree of resistance to all currently approved tyrosine kinase inhibitors.19 Ponatinib may be the item of a computational and structure-based approach to the design of a small-molecule tyrosine kinase inhibitor.
