She finds that she enjoys speaking with physicians and nurses about a vast array of tests, ranging from DNA methylation testing for Prader-Willi/Angelman Syndrome to immunodiffusion testing for Aspergilllus antibodies.
MLH1 methylation testing requires specific analysis of CpG islands in the proximal promoter region because other regions do not correlate as well with loss of MLH1 expression.
6 January 2010 - Belgian molecular diagnostics company OncoMethylome Sciences (EBR: ONCOB) said today it will perform MGMT gene promoter methylation testing in a Phase III clinical trial of Avastin in newly diagnosed brain tumours.

Although real-time PCR-based methylation testing for FXS is available (12) and is specific for FXS males carrying the FM with a methylated FMR1 CpG island located 5' of the expansion, there is currently no real-time PCR-based test that can be used to predict specific cognitive and behavioral impairments in female carriers with expanded FMR1 alleles.
